I'm having an odd problem with volts. When I have my headlights on with turn signal and brake, my volts drop to about the red area. At normal idle with no lights I'm pushing 13 volts and nothing ever higher. I tried a new alternator and I have the same problem. I checked for any loose grounds and my wires along the long tubes, nothing there. I had to mess around with the stock wiring harness coming off the battery and I put in an inline 30 amp fuse to replace an existing wire that I think was a fused link thinking it would work. From the fuse holder all the way to the connector on the harness gets very hot and melts the fuse, not blow it, just melts it after running the car for a while. I was just wondering if someone could snap a pic of the wires coming off their battery and leading to those harnesses pictures below:
any help is greatly appreciated
