# How many amps does a solenoid draw

Solenoid valves are available in a variety of DC and AC voltages. The common DC voltages are 6, 12, 24, 120, and 240 volts. The common AC voltages at 60 Hz are 24, 120, 240, and 480 volts. The common AC voltages for 50 Hz are 110 and 220 volts coil, it might typically draw 8 to 10 amps during engine cranking. An int eresting aspect of solenoid operation is that it can HOLD a force with a small fraction of the cur rent required to STROKE the same force through the length of its travel. Once the armature bottoms-out it's capable of holding many times the force needed to initially. Inductive loads are tricky. Initial current can be quite high. Starter current of 200 amps, possibly approaching 400 amps are quite possible. Temperature matter as well. Then to if it's a slow-blow or a fast-blow fuse will matter. I'd guess to use a 20 amp for the solenoid but that would be for a fast-blow fuse. I suspect auto fuses are slow-blow

### Typical Voltages & Wattages for Solenoid Valve

1. Think you 'll find the solenoid has only one coil - cheaper that way. The coil will probably be less than 10 ohms - so will draw more than 1 Amp. I'd think less than 5 Amps. But the load is highly inductive.. and that inductive back EMF is what kills the relay that drives the solenoid.. not the current it draws
2. The solenoid manufacturer says the four nitrous solenoids on one stage take 26 amps. When we test fire my box to activate the stages while the engine is running and the nitrous bottles closed, everything works fine. On the race track my box will open the first stage fine but then not open the second stage
3. Normal starter draw is 60-150 amps depending on the size of the starter. The solenoid should draw between 8-10 amps
4. Since no one has responded with an answer to your question how much amperage goes to the solenoid may suggest no one has measured it. The presence of a heavy wire (10 ga I think) to activate the solenoid suggests draw could be significant. No one has suggested it is bad to install a relay
5. The short of it is that it takes 8-10 amps to hold the solenoid in place while starting but the draw can spike to 30 amps while it is engaging

Solenoid current draw is around 30A. The starter solenoid performs two tasks; to switch the very much larger starter motor current (300+ amps) AND to engage the starter motor's drive pinion. A solid state relay (SSR) will switch faster than a mechanical relay but is more expensive, especially when allowing for engine compartment temperatures Remember watts = volts multiplied by amps (W = VA), so if you have only 12 volts the ampere or current requirement will escalate. For example 12 volt solenoid valve with 15 watt coil will draw 1.25 amps and if connected to a battery will have a significant power drain and will need topping up according to the power usage

The solenoid may operate with 12 volts but the amperage going to the solenoid coils at 12 volts will be twice as high than 24 volts. The coil wires of the solenoid are designed for a certain number of amps at 24 volt. Click to see full answer. Keeping this in consideration, can you use a 24v solenoid on a 12v system They do not draw much amperage at all. I have used 4 actuators and used a 15 amp relay inline and still didn't blow the fuse. The amperage is less than 3 amps for sure. Jeff Velocity Custom Home Theater Mobile Audio/Video Specialist Morden, Manitoba CANAD A good starter will normally draw 60 to 150 amps with no load on it, and up to 250 amps under load (while cranking the engine). The no-load amp draw will vary depending on the type of starter. If the amp draw is too high, the starter needs to be replaced. Click to see full answe

### How many amps does the starter solenoid draw? - PeachParts

1. I am not saying fit a relay Just pointing out your poor understanding. 80 amp is not uncommon for a solenoid ok i may of taken the extreme and not apllicable in this case.go on find a solenoid on a starter that draws less than 10 amps post back when you find one I tested several in my down time all were round the 19 amp momentarily then sat at.
2. The starter solenoid pulls at least 20 amps (I measured the current draw), I would add a relay and have it triggered by both your ignition switch and the pushbutton. That is the way the Painless Wiring starter relay I installed is wired, kills 2 birds with 1 stone and it works very well
3. Using a factory PMGR starter, they pull 1400 watts, so you can do the math. Remember there is a spike, and the cranking voltage drops for your calculations, but 200-250A is typical in surge, drops to the 120-150s and then climbs rapidly with heat and voltage drop
4. anyone know how many ohms, or how many amps, the starter solenoid draws, and how may amps, either individually or as a pack, the glo plugs draw. I am reading my glo plugs at 1.1, 1, and .9 ohms individually and about .4 ohms as a pack. That looks to me like it should be drawing like 40 plus..
5. The solenoid has 0 amp draw from the ignition switch, all the ignition switch does is ground the solenoid by closing the ignition circuit. The only amp draw on the ignition switch are: 1. gauges/instruments and their lamps (about.4 amp per gauge lit up) 2. carburator choke (about 5 amps) and this is a temporary loa

### Anyone know how many amps a Bosch starter solenoid takes

• The amount of load also contributes to the amp draw. The more load you put, the harder the winch functions. A basic model with a single wrap of winch cable would typically draw around 250 amp when the line pull is 4500 lb. Draining the Battery Powe
• g the solenoid is a basic single coil type, to draw 0.5A at 12V it should have a resistance of 24 Ohms (12V/0.5A). You measured 4V across it, which suggests an actual current draw of ~167mA (4V/24Ω). The transistor is limiting the current because it doesn't have enough gain to turn on fully
• IF you measured 4 ohms then that solenoid should draw about 3 amps. Then try energizing just the solenoid with a jumper (FUSED) and let it go a while to see if on heatup it draws more which might indicate an internal short. IF that is the case then a new one may be in order. If it checks out ok then look elsewhere
• starter on a bench draw 80-90 amps ,in the vehicle 200-350 amps. The solenoid itself does not draw much, the starter motor on the other hand does. Also the lower the state of battery charge the higher the current will be. You're just jealous because you can't hear the voices

### Solenoid amperage question All About Circuit

I can measure the actual draw, but I don't know how it compares to a typical winch solenoid and I'm struggling to find out what the cheap remotes are rated at. The Lodar I have switches up to 15 amps, but it's also ten times the price of the one I am looking at, so assuming the cheap ones can cope with the same might be silly Regarding this, how many amps does a Chevy starter draw? Most GM starters are free speed (no load) rated for 9 volts and will draw between 50-95 amps, so elnomad and onovakind are absolutely correct in stating that the starter could draw as much or more than 200 amps depending on the load (mechanical component condition).. Also, how many amps does a starter solenoid draw

For high amp draw applications such as winching, I find it more relevant to look at the battery's CCA rating (cold cranking amps). The CCA rating is an industry-standard that tells you how many amps (A) the battery can provide for 30 seconds, at a temperature of zero degrees Fahrenheit, while maintaining a voltage of at least 7.2V Weathermatic thinks if I replace the solenoid with a new one that should it should reduce it to around 1.2 amps and allow it to work fine. The solenoid vendor doesn't know how many amps a new one would draw and is convinced no electronic controller will work with them

If the DMM goes to 0 Amps replace the solenoid. Measure the current from the solenoid control circuit in the PCM harness connector to ground for 2 minutes using the DMM J 39200 on the 40 Amp scale. Does the current draw measure less than the specified value shown but not 0? 0.75 A . Go to Diagnostic Aids . Go to Step 4. Except, having two propane tanks (I have a catamaran, so two hulls to heat) means using two solenoids that each draw nearly an amp on their own. This doubles my electrical draw for heat on a limited house bank. I'm hesitant to eliminate the solenoid for obvious reasons but looking for another way around the problem Yessir I agree I was under the impression that the pull coil was much greater than 14 amps, I am still baffeled @ the fact that my old solenoid out performs the brand new one from larry b. I must give credit, the new solenoid pulled for roughly twenty cranks and then was placed in the same state as the old one Seems to me that a solenoid in the injection pump should not use this much power. But I also notice that the harness does have a 10 gauge wire to power the circuit. Is my solenoid failing causing more than 25 amps of current draw, or is this a normal amount? If this is normal, then I will install a circuit breaker in place of the fusible link Posted: Thu Oct 01, 2009 4:32 pm Post subject: Starter solenoid amp draw Does anyone know how many amps the starter solenoid draws? I was going to add a relay in to shorten the current path but the fact that VW used 10ga wire for that circuit has me doubting the little light duty relay that I chose..

More than one person has said the starter motor will draw more than 100 amps. This post especially has my attention: the 350 amps were for about the first 2 seconds and leveled off to 220 amp continuous after that For a 24VDC solenoid coil, 1.17 Amps looks correct. When current is flowing, the rated 28W will be dissipated as heat in the coil winding. If you have several of these in a small enclosed area, the heat build up may be excessive. Think about adequate cooling when designing/implementi ng your project to maximize solenoid lifetime and reliability. I have a 12VDC solenoid and I was trying to measure amp draw. Unfortunately I dont have a 12V battery handy. So I connected it to a 9V-6xAA battery pack. I first measured the ohms across the terminals of the 12VDC solenoid and got 43Ohm, which would suggest its a 285mA valve Posted 10/14/2013 00:49 (#3382255 - in reply to #3382154) Subject: Re: Delco Starter Solenoid amp draw Hagen Brothers farms,Goodrich ND WTW - 10/14/2013 21:40 A much better idea is to connect your ignition switch to a Ford starter solenoid on the firewall

Starter Solenoid 10-12amps. Starter Motor 150amps when cranking 180+ amps on Initial crank. Central locking Solenoid (each) 3-4amps Non Standard. Power Windows 20-25amps Non Standard. 1000w Amplifier 85amps Aftermarket for High End HiFi Syste How many amps do electric chokes draw? Discussion in 'Engine & Transmission' started by Doc, Dec 21, 2008. Doc Well-Known Member. Messages: 2,911 Location: Gunnedah. Coming home from Queensland today and pushed for time we had a breakdown in Yetman. (pop. 37) Stopped for lunch then restarted (first crank on a hot engine) and setting off down. If 250 watt heater is constantly running for 12 hours lets say how many total amps will that draw? Reply. LearnMetrics. 20th December 2020 at 11:21 am Hello there, the amperage remains constant. 250-watt heater on 220V will draw a bit more than 1 A. 1 amp is, by definition, 1 C (Coulomb) per second. In short, a 250-watt heater draws about 1 A.

How many watts does it take to run a pool pump? It's not uncommon for a 1.5 horsepower pump to use 1500 - 2000 watts. This is unfortunate, because most pools only need 1/4 to 1/8th horsepower for circulation. Higher power may be needed for tasks like vacuuming the pool. What size breaker do I need for pool pump? 20-amp OHV Briggs 14.5 HP single cylinder engines draw around 300 amps when the compression release doesn't work as designed. If your solenoid is good it might be simpler to hot wire the solenoid by running wires from a spring loaded toggle switch mounted on the instrument panel

So, if you divide 1500 (watts) by 110 (volts) you end up with the maximum current the coffee pot will draw, or in this case, 1500/110 = 13.6 Amps. Now, remember this is the maximum current the coffee pot will draw. In reality, it will draw a lot less when it is just keeping your coffee warm, but when it is perking the coffee, it can be. It is possible the starter is pulling too many amps from the battery. As a result, there is not enough voltage left to power the ignition system and fuel injectors. Normal Starter Amperage Draw: A good starter will normally draw 125 to 150 amps when cranking a four cylinder engine. And, 150 to 175 amps when cranking a V6 engine

Dishwasher Amp Usage. The amount of amperage a home dishwasher uses will certainly vary on the brand and model. As you can see from the list above, the amps used from popular brands fall in the range of 6.6 amps to 15 amps. No matter the brand, your dishwasher will be needing a 110 outlet unless you choose to hardwire it into the circuit Now, the starter motor used in most vehicles is a power-hungry device. To start spinning, it can draw from a few to many amps depending on vehicle type and make. This is a very high current that requires thick cables to heavy-duty components in the starting circuit. The ignition switch comprises delicate parts and very thin wires The 4-terminal solenoid shown here is typical of many used in the industry. Club Car uses one that looks different but functions the same. Forward and reverse switching two 6-terminal solenoids must be employed along with a 3-way (reverse, neutral, forward) 10 amp minimal key switch The question asked is: How Many Amps Does a Subwoofer Use? The Amp Factor. Some of the main factors by which the Amps can be determined are discussed and explained below: The rating of the Amp is measured by the impedance (measured in ohms) that the Subwoofer Power Amplifier sees as the load on its output That makes it about 30 Amps to the solenoid when there is no resistor in the way. I think that the solenoid current reduces when the starter is engaged. However, I am fairly sure that the 30 amps is very small compared to the full starter motor current. I think that 300 amps is a better estimate for that car

### GM Starter Solenoid Amp Draw Hot Rod Foru

The coil could draw as low as 2 to 3 amps, but when the coil is energized, this causes the large contact to move and it connects the two large posts on the magnetic switch. Now power to the cranking motors solenoid coils is provided from the batteries On the amperage chart above, we have charted the maximum estimated amps, an AC unit of 5,000 - 18,000 BTU is estimated to draw. Example 1: You can see that the 5,000 BTU unit (be it window AC or portable AC) draws a bit more than 5 A. Example 2: How many amps does a 12,000 BTU mini-split use? We can see from the air conditioner amperage chart that it draws about 13 A With Ignition On, the Starter Solenoid used as relay would draw maybe half of what a starter would draw. Waid View attachment 748787 View attachment 748788 View Even the Volvo is rated for 30amp only. I have bunch OEM Bosch 30 amp relays and I am going to play with it to see how hot it get when I trigger the high speed circuit. I will start by telling you what I have: 98 chevy 2500, stock alt, 2 one year old dura-last gold 900 amp batts, and a painless dual batt isolator, and a meyer E 60 pump. How many amps does the plow motor draw? I never have had any problems the last two plowing seasons but the lights do dim a bit. The system is wired with 2 gauage welding ground.

Here is what I have on the starter draw.....pretty high loads, but it can vary quite a bit. Starter Motor Diameter: 3.4 Current Draw Under Normal Load: 230-630 AMPS Normal Cranking Speed: 150-200 RPM Minimum Stall Torque @ 2.5 Volts: 27.5 ft-lbs Max Load: 2400 AMPS No Load: 170 AMPS Brushes: MFGR. Length = 0.71 Spring Tension: 122 o Divide the battery voltage by the resistance and there's your amperage draw! It's that simple! Example: A typical transbrake solenoid draws 1.4 ohms resistance. 12 volts divided by 1.4 ohms = 8.57 amps As long as you install the Battery Isolation Solenoid, # TR118665, correctly (see photo) and the items you are powering on the battery isolator output circuit does not draw more than 80 amps you will not have any problems. In most cases the battery isolator is installed on the charge line going to a trailer connector at the back of a vehicle and this circuit is used to maintain the trailer.

### Starter Solenoid current draw Team Chevell

I am going to Chicago for two weeks. I have a model s 85. I will have to put the 14 50 outlet in my dads garage when I get there. But if the wires going from he house to the garage are not at least #6 wire then I will not be able to use the 14 50 I will have to go with a 40 amp or 30 amp maybe even a 20 amp. so how does the Tesla know how many amps to pull Automotive relays are typically 150-200mA (72 ohm coil). Smallish reed relays with 12V coils are in the 12mA range. (1K ohm coil). As I hint above, relay specs are typically given in coil resistance How Many Amps Does a Gas Water Heater Use? A gas water heater with a tank will require 30 amps of electricity, which usually does not require any kind of modifications to the home's electrical system-even for older homes with only a total 100- or 200-amp service. A tankless unit that runs on gas will require a 120-amp breaker

AC Motor Full Load Amperes HP 200 Volts 440-480 Volts 5 17.5 7.6 7.5 25.3 11 10 32.2 14 15 48.3 21 23 more rows How do you convert HP to amps? Given horsepower and volts, it is possible to calculate amps. The calculation of amps uses Ohm's Law, which is amps times volts equals [ The initial starting current (I) is therefor high (greater than 240 Amps; From Ohms Law I=V/R =12/0.05). this is the peak starting current and will only last a fraction of a second. As the starter motor rotor begins to turn, the electric fields of the stator and rotor coils will interact to produce a back EMF which is an internal voltage.

### Current from key to solenoid of starter motor relay

Re: How many ampers does starter take? 12-12-02 03:05 AM - Post# 140309 In response to At 746 watts/hp, a 100% efficient 2 hp starter would draw about 125 amps at 12v. If the starter is only 75% efficient, it would take 166 amps to get the same 2 hp The current draw by the coil of a Bosch relay is ~0.160 amps (~75 ohm coil). In an AC relay coil, the resistance does not solely determine the current flow through the coil because the coil has inductance

### Starter solenoid current? - Google Group

The contacts should be rated for at least 10 amps at 12 or 6 volts DC (if the max contact amperage is rated at a higher voltage, it should still be at least 10 amps). Get the wire that you need. You need to make up 1) a ground wire for the relay coil; 2) a wire to go from the relay to the solenoid and 3) a wire to go from the relay to a power.

### 12 Volt 12v Solenoid Valve - Connexion Development

There is a thread here and I think it is a 'sticky' that is a table to show you voltage draw to the required wire gage. First off, remember the length of the wire compared to the amp draw is both ways. Meaning the positive and negative side of the circuit. Secondly, this again isn't a black magic. If you follow this table you will be ok How many amps does a stove draw? Most residential stoves draw between 30 and 50 amps. Does a gas range need a dedicated circuit? A gas range doesn't need a dedicated circuit, but it's not a bad idea. Beyond the control panel and pilot light, there are few electrical components of a gas range For the record, if you know these 2 data (voltage and watt), then you can use a formula to find out the amp. And, the formula is 'amps = watts/volts'. So in that sense, if your PSU has a watt rating of 500 watts and the supply voltage in your area is 120 volts. The amount of amp your PC will draw will be (500 watts/120 volts) = 4.16 amps

How Many Amps Does A Treadmill Use? Generally, treadmills need a 12 to 20 amp with an isolated ground/neutral to cater to the requirement of the power. This implies that the outlet that you have used to plug in the treadmill should not connect any other device running on it How Many Amps Does A Cordless Drill Draw? Now, to figure out how many amps your cordless drill uses, let's go back to the pipe analogy. The more pressure (volts) the water is under, the faster it will go (amps). So, a 20v cordless drill will always draw more amps than an 18v cordless drill Cranking cold amps (CCA) are similar, but they are recorded at 0 degrees Fahrenheit. CAs work best when it comes to short bursts of intense usage like starter motors. Amp-hours refer to the number of amps delivered for a fixed number of hours. For instance, a 100 amp hour battery consumes 1 amp to deliver 100 hours, or 20 amps to deliver 5 hours Amps calculations. The current I in amps (A) is equal to the voltage V in volts (V) divided by the resistance R in ohms (Ω): The current I in amps (A) is equal to the power P in watts (W) divided by the voltage V in volts (V): The current I in amps (A) is equal to the square root of the power P in watts (W) divided by the resistance R in ohms. How Many Amps Does a Refrigerator Use? It is possible to understand the power consumption of household appliances by learning about wattage and amperage concepts. According to the United States Department of Energy, refrigerators have an average wattage of 725 watts, which, at 120 volts, computes to an amperage of 6.04 amps It's unlikely your PC will draw that much. It'll probably just draw 450 W or so if it's a typical gaming PC. If your PSU is 90% efficient at that load, then it draws 500 W total. 500 W / 120 V = approx 4.17 A. 500 W / 240 V = approx 2.08 A Some inputs are 115 V or 230 V
