Quote: If you bypass the ammeter completely and run wiring direct from alternator to battery, couldn't you use 8 gauge wire with a 12 gauge fusible link??
And what about a 1 wire alternator?
Yes and yes. 8 guage wire and a 12 guage fusible link would be good up to 100 amps or so. It would also work fine with a single wire alternator... with volt meter to monitor system condition.
