Over charging now, no ballast resistor

Oldmanmopar said

If the blue wire going to the voltage regulator shows low voltage will make it overcharge. It comes from the ignition switch to the bulk head

Then from the bulk head it goes to a soldered 4 way connection in the harness. From there it splits goes to the Alternator, voltage regulator, ballast resister, electric choke, Somewhere that wire is shorted or has a bad connection.

I usually find it is at the bulk head being dirty but there has been times I found the soldered joint at the splice is broke. I believe if you find your Alternator and voltage regulator are good it will be that wire.

Get a volt meter and check power from the ign. to the splice and out to its use under the hood to find where it is losing power from a short or broken. CHECK THE BULK HEAD CONNECTION.

Hi, Steve. I've posted this a zkillion times. It can be any terminal, crimp, connector, connecton, including the contacts in the ignition switch itself, and they add up if more than one, in the complete path from the battery to the VR IGN termnal

Generally (factory wiring) the path starts at the battery, to the starter relay "big stud," through the fuse link (LARGE RED) From then the problems can be: the LARGE RED going through the BULKHEAD CONNECTOR, to the AMMETER, including the wire end terminals, the ammeter itself, out of ammeter on the LARGE BLACK, to the WELDED SPLICE which fails rarely but can fail, to the IGNITION SWITCH CONNECTOR, through the switch itself, back out on the DARK BLUE ignition run, back out through the BULKHEAD CONNECTOR, and to the ballast and at some point a splice to split the blue off to whatever loads it feeds, including the ignition system, VR ign terminal and the blue field wire at the alternator.
