I did a battery relocation. I'm running a 4ga to the alt and starter, and then 2 8ga to the 4 12ga wires. I wanted to ask would a 100amp fuse hold on the alt/starter feed, there is no other circuit on this feed.. I have a 150 circuit breaker but its 42volts so will not trip (tested already) in a 12volts system (duh) so was just thinking 80-100amp fuse... I wana say the alt is a 80amp...
