Del Help! Cuda not Charging

OK someone has converted your car to the 70/ later alternator / regulator

I tend to separate the system into blocks

The charging output circuit, IE the charge wire, bulkhead connector ammeter if still in the circuit

The field wireing

Alternator good or bad

Regulator good or bad.

=============================

For a first "quick check" and BECAUSE you have an adapted system, you need to discover which alternator field wire is +12 ignition, and which is the VR

So unplug the VR connector, and turn the key to "run." Unplug both field wires and check for voltage. One will be 12V hook that one back up. Does not matter which field terminal is which on the alternator.

Now take a clip lead and ground the remaining field terminal. Start and run, look for evidence of charging, and post back
