alternator

No need for a ground. Any problems with the gauge cluster? If the warning light for the charging system is not in-circuit I think you lose the power that excites the alternator field.

Do you have power at the smaller post (D+) with the key on? If not you can jumper that and see if you start charging. Careful though if it's shorted you might get some sparks so don't use a piece of coathanger wire.
