Re: Checking for electrical draw

Need a clamp on ammeter. They can read a lot higher amps.

This might sound dumb but did you replace the fuse?

Re: Checking for electrical draw

To test for electrical draw you will need an ammeter. A clamp on style is what you will need. Clamp it onto the positive cable going to the fender mounted solenoid. The meter will indicate how many amps are being drawn at that time. It is not uncommon to see up to a 2 amp draw in a vehicle normally. You then pull one fuse at a time to determine which circuit is causing the draw. From there you will need an electrical schematic to be able to trace the wiring.

Yeah, my meter has a 10 amp setting, I really dont feel like buying ANOTHER meter just for amp draws

Re: Checking for electrical draw

I probably have one I can loan you. Flat rate boxes aren't that expensive but once you ship there and back you can find a good used meter.

Re: Checking for electrical draw

When I say I have one to loan, it is one that will do amp draw.
