How much current does the coil draw?

Less than my clamp-on ammeter would respond to. I'd have to disassemble the circuit and put a series meter in the circuit to find it for certain. If you call the manufacturer they probably could tell you. They do have a web site. Just a guess but I would think it wouldn't be more than about 20 mA at 120VAC.

Howdy Andrew, it would appear that the instruction leaflet that came with coil is a bit confusing, using this on a MSD unit producers up to 48,000 volts, however when fitted & checked, it runs around 39825 to 40125, so my answer to you is 40,000 volts, I'm sorry if this confuses you, these are really great units, my motor is heavily cam'd & carb'd and the high voltage has settled the idling no end, anyway, good luck, Jim

I'm pretty sure its single coil 4 ohm. But mine came with a blown voice coil out of the box so I never got to wire it up. Box is decent enough though.

Does not take much current at all. Ive loaned mine to my mother and she uses it for a whole 9 he shift and has no problems at all.

1.5V/LR43. I bought mine in a dollar store. Lasts a long time. Be sure the magnet is on tight. Bit finicky to set up but once it's done you'll love the unit. Have fun!

I soldered a short piece of #14 solid wire to the two voltage leads and covered with heat shrink tubing. Then I put these leads under the lugs of my sub-panel(feed from my generator) to read the incoming voltage from the generator. The meter comes with a coil which is placed around the circuit wire, this generates a very small current in the coil which the meter converts to the actual amperage, therefore the coil wire is carrying very little current. I hope this helps.

It's just momentary power for the solenoid, but a typical inrush current is about 25 amps and then holding current is 10 amps.Again, this is typical of high power solenoids to draw the contactor into place with minimal arcing.Read the comment to the answer about what that schematic is about in another question.DO NOT try and wire this solenoid per that diagram. No matter if it is a latching or standard SI solenoid, that drawing is wrong. Dead wrong.

The package lists 15mA but measured only 11mA of parasitic draw. The draw is because of the led, and is pretty good, but I added a switch to turn it off. My camper has about 100mA parasitic draw which is high when compared to a typical car of maybe 30mA.

Usb is 5Volts with .5A maximum draw. My multimeter won't even measure the current it's drawing so I'm not sure the exact wattage. So by using the above figures... 2.5 watts maximum although I guarantee it's definitely less than that. Hope that helps. The actual unit itself has no power listing so that's all I can figure for that.

Coil Specs from MSD's web page. Hope that helps. Turns ratio: 100:1 Primary resistance: .7 OHMs Secondary resistance: 4.5K OHMs Inductance: 8 mH Maximum voltage: 45,000 Volts Peak current: 140 mA Spark duration: 350 uS Weight: N/A https://www.msdignition.com/Products/Coils/Stock_Replacement/8202_-_Blaster_2_Coil_Hi-Performance.aspx

Easily, normal draw is under 15 amps. Set one up in a camper on a 15 amp circuit and at full output the fuse never popped

Watts = Voltage x Amperage so maximum current draw would be 6v x 0.5a = 3 Watts?That either really efficient or my math is broken.

Jennifer,A 300 watt inverter is way too small for a hair dryer. What is the amp draw of your hair dryer.Joe

The coil that pulls in the contacts requires 12 volts - 24 volts will burn up the coil. you need a contactor that uses a 24 volt coil. the contacts themselves don't care about the voltage.

Check the capacity of the circuit you have it plugged into. This needs to be on a 20A circuit as it will draw up to 17A, depending on your power supply. That is, BY ITSELF on a 20A circuit.The MINIMUM current draw will be 15A and that is already too much for a 15A circuit, you will likely blow the circuit. If it doesn't blow the circuit as soon as you plug it into a 15A circuit (and turn it on), there is something wrong with your wiring.

I don't know the minimal current necessary, but mine triggers with 12v when hooked-up to my truck battery.

Very low. I believe it was less than 1.0 amp. Like 0.6 when I did the math but on the safe side it was 1.6 at the very most. My memory is failing me at the moment but im pretty sure it was less than 1.0 amp. Hope this helps
