What is you power package? engine and drive. There is a "One wire alternator" The heavy gage wire goes from the alternator to the same post on the starter that you attach the battery to.
I have about 5,000 dollars worth of receipts for the motor...and they say it is a 3.8 4 cyl...
The alternator is not a marine(my friend is bringing me one to remedy that).
As i stated..there are no wires anywhere that I can see that attach to the alternator.When i brought the boat home...I put a toaster or tester if you will on one of the batteries and it is dead.
The motor starts like a charm,but I need to get the charging system figured out.
(the wiring is all messed up,but i am sorting through that...LOL)
