So I've been hunting down an annoying problem with my truck. I was having major issues with the truck not starting, then changing something out and it would start, then it wouldn't start a day later. To date I have replaced the battery (new optima), the alternator (new), the starter (known good), timing chain (it was a shot in the dark), and the distributor (known good). I thought I had the problem solved finally. The truck ran great for a few days, then when I went out to go start it the battery was dead, again. I checked a couple of things and this is what I came up with:
The alternator puts out 14.5 volts, at the back of the alternator, but I only get 13.6 at the battery.
When I run a multimeter between the negative post and the negative cable I get a 3.5 amp draw. (today, 2 days ago it was a 2.5 amp draw). I narrowed it down to the ignition fuse. When I take that one out, all the draw goes away. I pulled the distributor feed, still had the draw. I pulled the ignition switch feed, and still have the draw.
Where else should I look for the draw on the ignition feed? I can't seem to find the source of the pull?
I am running a remote starter solonoid for the starter (it was a cure for a previously thought starter heat soak issue, which actually wasn't a problem at all), but it doesn't appear to be the culprit either.
Please, any and all advice would be greatly appreciated. Thanks in advance!
