Alternator help
 

Trying to wire an '87 Toyota alternator to the race car and I am stumped. Have one large terminal (bat.?) and at the rear of the alternator there are 3 plug connections, 2 vertical and 1 horizontal. Anyone have experience with this one? Thanks, Bob Michael.

I energize one of the three with a toggle switch
on dash and the big one to battery. I will look at which
one when I get home later in week if no one else
tells you.

Bob,

I believe this diagram may be what you are need for a Nippon Denso alternator.

Thanks, Larry and John. I'll hook it up tomorrow and try it. So I'll leave the no. 2 connection open. I even got a toyota wiring diagram and still couldn't get it!! (electronically challenged!) Bob M.

Bob, the # 2 is the S terminal..It's used to sense the load at battery..Not necessary for your application.

Thanks, Mark. Also thank you for the sponsorship of the class nationals. It's shaping up to be THE event for us. Bob M.

YAY!!! It works! Thanks guys. It works the same with the light wire unplugged as well. You wouldn't believe how many times I wished I was smart ! Bob Michael.
