1965 Dart Charging System Question

I never can remember...........does your car run the ammeter through the separate very large posts through the bulkhead? some early A's did this. if not..........

Generally the voltage drop path for Mopars is this:

Battery...........starter relay big stud..........through fuse link..........through bulkhead on RED ammeter wire..........through ammeter......out the BLACK ammeter wire..........to the under dash WELDED SPLICE..........branch off that to the ignition switch connector............through the switch........back out the connector on (usually) DARK BLUE "ignition run"...........back out the bulkhead connector into the engine bay.

EACH POINT above that is a connection is suspect and there might be more than one. For example, drop might be right IN the igntion switch itself, and or in each of the connector terminals.

I've posted this before..........one way "around" this is to electrically cut the dark blue "ignition run" coming out into the engine bay.

Use the end coming out of the bulkhead to fire a relay.

Connect the engine bay end of that wire to the load contacts

Connect the feed contacts to a fuse/ breaker coming off the starter relay 'big stud.'

There are only so many causes of over charging

1....Voltage drop in the "hot" side harness, causing the VR to get low voltage
2.....Voltage drop in the ground side, the VR MUST see a good ground back to the battery
3....In rare cases, battery problems
4....A VR that is out of calibration, especially if the old mechanical type. Most new replacement ones are solid state, and most either work or not, but there can be exceptions.
