I have a beautiful GXL/TII which I built myself. Running a big turbo, bad ass tube manifold, Haltech E6k, tons of fuel, and other goodies. Anyways I'm having electrical problems! This did not start abruptly following my Haltech install. It started about 4 months after. I get excess voltage drop when turning on accessories. When i turn my heater blower motor on my voltage drops to like 8 volts and it eventually flips the resetable fuse (breaker) in the stock fuse box, TODAY i tired to close my sunroof and it heated up the positive batter cable so much that down by the starter it caught on fire due to some oil residue it had on it.



My cars alternator puts on 14-14.5 volts, the battery has been load tested, the negative battery cable was replaced because of a bad terminal clamp, i checked the positive for voltage drop and got zero volts. I ripped aparter the stock chassis harness (that has the pos/neg batt. cables going through it and checked it out and re-wrapped it. Please any ideas!!!

i'm thinking bad connections at the battery cables? heat = high resistance?

Thats what i was thinking. I replaced the negative cable because of a bad terminal clamp. I unwrapped the harness and checked the positve and it looked fine. I'll go ahead and R&R that one too i guess. Ive checked it for voltage drop, (meter on volts, B+ on battery to starter B+) and i got 0 volts. usually you see like at least .1

thanks for the reply bro.
