Hello everyone,
I'm trying to locate the source of a parasitic drain on my 94 Cheyenne 1500 W/T. It's reading 300 miliamps with the key out of the ignition. I've pulled each fuse individually and didn't see any drop in current. I disconnected the alternator, no change. There's nothing aftermarket added to the truck. The engine ground is fine as well. I've tested just about everything I could test and I'm getting a bit tired of jumping the thing after just a day of sitting. Could this be a starter issue? It turns over fine when charged, but that's the only component that I haven't messed with.
