Hey guys. I recently replaced my brake booster on my El Camino. While working on it, my interior lights kept flickering and sometimes theyd go out completely. I ignored it and got a flashlight. After I was done, I noticed my battery light was on, even with the doors closed and ignition off. I scratched my head and hit the ignition. Nothing. No headlights, tailights, starter, nothin. Just my battery light works? So I messed around a bit and figured it might have something to do with the wiring from my tranny I recently removed. I touched a ground cable that was attached to the firewall to the engine and it sparked. WHAT THE HELL?! MY FIREWALL HAS POWER?! Sure enough, everytime something metal touched my firewall, it sparked. I talked to a guy who knows a thing or two and he said my terminals might need cleaned. The same thing has happened to him. So I wire brushed everything from the battery to the solenoid. Nothin. Whats going on???!!!
