1995 S-10 Blazer Electrical Problems

[nmoran429]

I have been having some electrical problems with my truck. It seems that if I leave my truck for more than 12 hours plus, it has drained the battery to the point where i need to jumpstart it almost everytime I start it. I have replaced the battery nearly 2 months ago, replaced the alternator a month ago, and just recently replaced the serpentine belt 2 days ago because it was frayed so badly. But still I had to jump the battery today before I ran it. I splurged and ran out and bought one of those rechargeable emergency battery boosters for it. I do have some accessories to the battery, but I dont think it would be the problem. I have a subwoofer box with only a 450 watt amp, underbody neons, and wireless fog lamps from Pep Boys. I took it into AutoZone the same day I changed the belt on it, and the battery seemed to be ok. I think there may be a short somewhere. PLEASE HELP!!

You have a parasitic drain somewhere.

Have you ever completely recharged the battery at all?

You can't boost and drive and expect the battery to be recharged.

You will have to pull one fuse at a time and see which circuit is causing the drain.

When I pull the fuses out of the fuse box, what am I looking for? I obviously need the truck to be running, right? No, I haven't recharged the battery. When I took it to AutoZone it seemed to have enough juice, but personally I think the attendant that was using the battery tester didn't know what he was doing.

No, the truck has to be turned off.

You need to be monitoring the current draw off of the battery and noting when the draw drops when a certinn fuse is pulled out.
