Dodge One Wire Alternator

My problem is the in my truck somewhere between the alternator and either regulator or battery the wiring is toast. Dad said the truck always charged fine until someone arced a set of jumper cables over never charged right again he replaced the regulator alternator and the part behind the ammeter in the dash. He had a old chevy 1 wire but i want to run a dodge alternator and alternator brackets.
If anyone has the wiring diagram for a factory alternator I could just wire it up with new wires to the regulator and the battery,ect.
I'm on a pretty tight budget so cheaper the better lol

The thing is the regulator/ alternator/ and associated field wiring may not be the trouble at all. It could very well be in the bulkhead connector/ ammeter, in which case if you bypass the ammeter, it won't matter if it's 1 or 3 wire

Does it charge "at all?" What exactly does it do that's wrong?

Here, from "MyMopar" is a simplified diagram of the regulator/ alternator wiring. That diagram does not show the ammeter/ bulkhead, but it does show the regulator. The far right terminal of the regulator goes to one field terminal. the remaining regulator terminal and the remaining alternator field terminal goes to switched 12V coming from the key. IMPORTANT that the regulator be grounded.
