Increasing Gauge Size of Alternator Battery Wire
I am installing a 150 amp alternator in my 66 Lemans. It has/will have dual pusher Spal fans, 340 LPH fuel pump. GV OD, amplifier, Dakota Digital dash, Progression Ignition. The car has a brand new M&H engine wiring harness with 12V wire for HEI and upgraded for an internal regulator.
The CVF alternator I bought may be used as a 3-wire or 1-wire. Since I have to use a 6 gauge battery wire for the alternator is it OK to attach the 3 engine harness wires to the alternator as the factory did, and add the 6 gauge wire in tandem, to the starter’s battery post? Or should this be wired in the 1-wire configuration? If so, is it OK to run the wire to the starter’s battery post. I’d prefer to do it as a 3-wire so I can make use of the new engine harness.
