His alternator has a lot of lead in it's pencil and nobody to write to. Am I getting this across...Vehicle wiring harnesses to the chassis battery restrict amperage horribly. The 4 gauge new wire must be dedicated RIGHT FROM THE OUTPUT STUD OF THE ALTERNATOR DIRECT TO BATTERY POSITIVE VIA A CHARGE DIVIDER AND CIRCUIT BREAKER. I don't read this stuff out of a book or put on a propeller beanie and play the part of Gyro Gearloose...I did it and do it for a living. As an engineer not a shoe salesman. Maybe I'm wasting my breath here.
Typically what size wiring does a stock Ford or Chevy alternator come with? In gross terms if your batteries are at 50 percent SOC with stock wiring how many amps can you pump into 2 GC batteries? With 4 gage wiring how many amps will you see?
