Ok. I know there have been numerous posts on this topic and I've read many of them. I've gotten lots of good ideas, but none have panned out for me, so...
I have finally decided to dig in and try to locate the source of my electrical drain that is leaving my battery dead after about 3 days of sitting. Previously, I had been using a battery cutoff switch, but I'm not a fan of "band-aids."
I removed the fuse to the courtesy lamps and then measured the amps at the battery. My ameter goes up to 250ma and it was buried. So, following previous advice, I began removing fuses and remeasuring. I eventually pulled every single fuse and was still left with the same drain (something higher than 250ma).
Then, I took the alternator and the starter out of the circuit. Still the same drain. Now, I'm without ideas. No fuses, alternator, or starter in the system and still showing a drain.
Pull the horn relay, if your horn hasn't been working. You are looking for things that are not fused thru the fuse block.
You're da man! I pulled the relay and things read perfectly! I love having a PC in the garage with constant Internet connection. Thanks to you, problem solved in less than 15 minutes and I didn't have to beat my head against the wall!
you have to either put the amp meter in lile with the battery cable or use it as a volt meter across a known value shunt. Best way is probly the in line methode. I have a Fluke Clamp on attachment for my voltmeter that allows a very simple quick clip on check. Check around with some of your tron type buddies, maybe someone has one. Or if your in the neighborhood,,
