I run a 105 amp one wire alternator. I run a 10 gauge wire directly to the battery fused at 60 amps. I'll probably never actually draw more than 40 amps total with the radio cranked, fan on, all the lights on, cigarrette lighter going . Your'e only going to pass as much current as the internal circuitry in the alternator will actually allow so i dont have any problem running a 10 guage wire there. I still dont know why guys run 8 gauge wire to their HEI ignitions. Ever see the wiring INSIDE one of those things?
