ECM/BATT draining my battery
I have a 95 s10 4.3L. My battery drains while not running. It usually takes about a day and a half to drain to the point where i can't start it. By trial and error i found out that if I take out the ECM/BATT fuse that it my battery is fine. What could cause this? Thanks.

Well this isn't exactly going to "help" but it sounds like you have some kind of parasitic draw. You need to get ahold of a wiring schematic and start checking draw at different points. Check what that fuse powers and slowly start eliminating down the line. Like I said it doesn't exactly "help" but electrical gremlins are the hardest thing in the world to diagnose, especially parasitic draws. It just takes time and the process of elimination.
