hi im after a wiing diagram for the alternator 4 pin regualtor......
please help me i cant find any imformation

oh i forgot its a 86 buick regal 3.8 v6 if it helps

I may have the book with the wiring diagram you seek. You have me confused because isn't the alternator on an 86 Buick built with an integral regulator? (built into alternator)
What kind of problem do you have , maybe I might be able to help.

The wire that go to the connector that connects to the internal regulator
If that helps

Am I correct in assuming that you have the alternator apart presently?
