Starting circuit wiring

My reasoning for running two feed wires through the firewall to the interior is to use one as the factory did. Feeding the "welded splice" to feed the ignition switch, fuse block, and headlight switch.

The other hot wire will be used to feed an auxiliary fuse block for future accessories.

I believe the alternator is 80 amps.

What size charge wire should I run from the alternator to the starter relay?

And what size fuseable link should I use to protect the circuit from alternator over charge?

Thanks again. Eric L

Fuse links for me are a problem, some of them are not specifically rated. IF the alternator is NOT a "one wire" a no8 would be plenty large. If it is, I'd run a 6

You need a fuse link that will handle alternator output without jeapordizing the wire you are using. What you want to protect against is "if" the alternator (diodes and stator) generate a serious short to ground
