AAW Classic Update kit -- ALT, BAT, and panel feed wiring - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm trying to decide how I want to wire the charging and panel feed circuits on my 69 C10. The kit comes with a "charging" sub-kit with 6 gauge (!) wire and 175 amp fuses that is total overkill for me. I'm actually considering using 10 gauge wire, which is one size larger than stock, or possibly 8 gauge, which I used on an 82 C10.

As for routing, I may just duplicate the factory routing from battery to alternator, but use a maxi-fuse instead of a fusible link near the battery. I do not want to feed the alternator and fuse panel off of the starter BAT terminal, because things are very tight down there with my headers.

What have you guys done?

The truck probably draws no more than 30-35 amps through the fuse panel with everything turned on. No killer stereo, power windows, or radiator fans. The Vintage Air system is powered directly off the battery through a breaker.
