Ok, what gives?? Electrical guys, step into my office.....

Ok, trying to trace down my .080 Amp draw. I have the following disconnected, and just made another check:

Alternator
Everything at the main distribution block (behind the battery, all the cars cables, NOT the battery cable)
Starter

Essentially, NOTHING hooked up to the battery. And the draw is STILL there!!!! The main positive cable is hooked up still, and I'm setting the multimeter to Amps, in line with the negative terminal on the battery negative terminal, and with the positive terminal on the negative battery cable.

WTF would be doing this?

Disregard

Ok, I'm the winner of the dumba** of the day award. The ONE thing I thought it couldn't be, was. My MSD Digital 6. That's my draw. Everything I had seen had shown it hooked up with the positive cable directly to the battery. I pulled that cable with the multimeter hooked up and my draw went from .080 to .000 amps instantaneously.

So, another question. Will the Digital 6 work properly hooked up through a switched source (I.E. plugged into the fuse box like most end up with the electric WP)??

Re: Disregard

the heavy gauge(10 or 12) red wire should go strait to batt 12v, the smaller red(16g?) should be switched 12v

Re: Disregard

Ok, I take it back again. I removed the MSD, and hooked everything up one wire at the distribution block at a time. The dual grey wire hookup was pulling about a .080 also. Funny thing is that a variety of items on each wire caused the problem, as I pulled all the associated fuses and tried one at a time by plugging it back in. Both wire circuits, a variety of fuses caused the draw. I hate electrical bugs.

And I'm also left wondering why the MSD would be pulling .082 amps when it's wired in correctly using the MSD harness.
