^ i like the mod to just run a parallel wire to the ammeter from the alt output (and likely a parallel wire from ammeter to FL). if my bulkhead weren't so burned up already i think that would be a great simple way to save the bulkhead and keep the ammeter.

on another note, checking for shorts. quick and easy way is to just check for continuity from the circuit to ground with the neg battery terminal unhooked?
ie, I unhooked the neg battery, then, probed from the neg battery terminal to the b+ post on my starter relay, infinite resistance. safe to assume no shorts to ground? still have this wired so that Alt goes to b+ on relay, also from b+ on the relay, a 10g wire into the cab through the firewall, not the bulkhead, and spliced into the power feed/ammeter feed in the wiring harness...
