Hey fellas, just thought I'd see what ya'll think. I'm stumped!
Last week during a cold snap, the battery died overnight. Replaced it and everything is working fine. I figure if it's the alternator that I'll get another dead battery soon. 4 days later (yesterday) the battery is dead in the morning again. OK I figure it's alternator time. Ordered new BOSS alternator (it arrives today). I take the battery out (it's a Walmart battery from the old V6), take it back to Walmart and am ready to pay for a new one. Really nice people there swapped it out under warranty for the 2nd time for free! Very nice. So I take it home, put it in the car and there's nothing. No lights, no dings, no clicks, absolutely nothing has power. I jump the car -- nothing. I take the battery out and take it back to Walmart again to get it tested and it's good. Take it back home, put it in the car again and test continuity on the wires. I have continuity between the negative terminal and the ground attachment points, and I checked continuity on the positive terminal to the 3 positive wires that come off and that was good so the giant fuse on the battery is fine. I test voltage to the engine fuse box and I have power. I check the big 80 amp fuse in there and it's good, alternator sense fuse good, checked a bunch of other fuses and found no problems.
I don't have any more time to mess with it so I had it towed in to a mechanic... a new one that I don't know b/c my regular guy is in the hospital. What could cause this? My fear is PCM or BCM ... but if that happens I wouldn't lose ALL power right? Things would just go haywire? ... I'm thinking it's gotta be a loose wire or fuse, right? Maybe alternator/alternator fuse?
It's so weird b/c I haven't done anything electrical recently. The only thing I did was replace the fuse in the BCM for the cluster b/c I noticed that my cluster has lost power overnight a couple times since I built the car... I was thinking I might have a parasitic drain before... was gonna test with the new battery. Prime suspect would be these stupid side pipe exhaust cutouts that were causing a short when we first put them in... (short fixed btw)
