Hey. This is my first thread to this forum but in the past I have found lots of useful information. I was wondering if there was any advice concerning an electrical problem. I have a 1980 Blazer (home built 383, Detroit locked 12 in the rear, ARB in the front, sm465/205, etc. to much to list) that I replaced the body on. There isn't on bolt on it that I haven't wrenched on. I reused the old body's harness on the new chassis. The truck runs great except for one thing, if it sits for three or more days, the battery loses it charge. I suspect a constant draw somewhere. It has a 140 amp alternator (new), and a Optima red top (new), good grounds between the body, frame, engine, battery to body, battery to frame, alternator bracket to the body. I had the charging system tested and everything is working great, including the battery. If I start it up everyday it doesn't lose enough charge to be a problem, but after about three it needs a jump. The stereo has a constant charge to keep the memory but this shouldn't be enough to drain it for a month. Any ideas on troubleshooting? ANY info would be appreciated. This is not a new problem, just something I have been dealing with since the truck was rebuilt. I runs GREAT, charges GREAT, just doesn't hold the charge. Thanks in advance.
