He guys decided to go with a new powermaster 150amp chrome smooth look alternator #37297-313. Received it today and noticed the plugs are different. Powermaster alternator has two prongs on its plug and my stock alternator has a plug with three wires and 4 prongs on the alternator. I was wondering if powermaster had a plug to adapt it but they don't. Powermaster tech guy told me I should be ok to just hook the 2 wires up to the post in the back and leave my stock plug unplugged. Not sure if this is what I want to do. I'm assuming that the wires for that plug go to the idiot light on the dash which won't charge the battery in its not plugged in. I do have the caspers field fix installed so I'm not sure if it's ok to run it with out the plug in. Any one else run into this situation. I posted a picture of the new alternator two pin and my old one and stock plug.
Powermaster alternator install. Different plus ?

Looks like that alternator is not made for a GN, just looking at that 2 prong plug should be enough to alert you
If the builder of the alt says to tie in the 2 prongs to the lug in the back , then the alternator will be putting out max volts all the time and boil your battery, I can only imagine your car going up in flames after driving down the freeway
That same plug is on my 67 bird and it uses a external regulator....
I would return it and get a 200 amp caprice alt

Yep I bit the bullet and paid the $419. Of course if you don't want chrome it's a little cheaper.

That alternator has the early style regulator in it. They haven't used that style in years. Send it back and get the correct one.
Probably a 1 wire alternator. They don't require a powered signal to start the charging. It will run without the plug hooked up. But you won't have the charge indicator light without it hooked up. I would also recommend getting the correct fit, but you could hook up the idiot light circuit with a harness from any part store for an old GM vehicle. The signal/reference wire needs to be left off or the alternator field stays powered and will kill the battery.

Wouldn't a 1 wire be just that. 1 wire not 2 wires in a connector and the battery wire = 3.
Op-
400 for a chrome alternator. Maybe I should sell one of mine!!
Have you tried your local alternator rebuild shop?
I'm selling a bunch of stuff, are you buying chrome parts?
