66 Valiant Electrical Issue?

I plugged the new alt in, joined the two alt gauge wires, plugged the ign switch back in and jumped the fusible link. Turned the key on and turned the heater on and....it worked!!

So that must have been the prob.

Regardless though, I did pull the dash harness and the engine harness and am going to do the modifying that's recommended and check for any questionable items. Not to mention there's prob a dozen or more bare spots in the engine harness.

Got a question. Can you still run the single field alternator when wiring up electronic ignition or do you have to go to a dual field??
