I'm having some charging issues, that as best I can tell can be traced back to a
resistance or breaks in the charging circuit. Specifically the wires that are part of the voltage regulator plug are frayed and corroded. (Alternator and VR all test good, but the juice doesn't get to the battery. I get 13.4v +/- at the A terminal of the VR, but it only shows 12.5 at battery.)
It appears that these are all part of the headlight wiring harness, so here are my options.
1) Leave it as is and install a 1-wire alternator with internal regulator. I figure that I can leave all of the factory wiring in place, and reverse this modification in the future if needed.
2) Replace the headlight wiring harness to keep it correct. Has anyone ever tried to replace the entire headlight harness with the car intact? I haven't jumped into it yet, but can I access the harness for removal and reinstallation without removing a bunch of other stuff, such as radiator, headlights, etc? It looks like the harness runs from under the dash all the way to the voltage regulator. Also, I assume that the correct harness would be for a '68 GT car to account for the fog lights?
3) Or, attempt to splice in a new voltage regulator plug and hope that these are the only damaged wires. I know that I can get just the plug.
Thanks in advance for any help!!
