Grounds checked. I also have multiple added grounds to lower engine noise in my stereo sys. This just happened after everything was working fine. All harnesses are new, and basically every part of my car is new. I got a Alt from a local alt repair shop. I bet that's the problem, just wondering if anything else could be happening. Just surprised the Alt. could die so soon. I will pull it again and get it tested. Just put it in a few hours ago after changing my only remaining old harness. Has anyone had all the dash lights come on with a dead alt.? Seemed to happen after hitting a bump, so I thought my old harness was dead.
