Alternator Question

[68coronetGLwannabe]

I have a new alt that a friend gave me. He said it is a high output one. My question is can you use one that has 3 wire connections on a car that has 2 connection? My car is a 69 Charger and has 2 conn. The other came off a 71 GTX and has 3 conn. Thanks

You will ground one field but it should work.

you can replace the isolation washer at brush/prong ( anyone of them ) with a metalick and done...

Cut the prong for safetty to save from plug your existant field wire at the grounded brush. Will short.

Or simply fit a terminal with a wire grounded, once again, to any of the brushes

When I removed the prong everything came out including the brush. Can you just leave that all out or do I need to do as said above? Thanks for your responses

yes, brush and prong is one assembly.

the metalic washer and cut prong method is just one option... can you keep the prong on it ? yes you can, I told just to keep safe you hook the wire coming from regulator there by mistake, because on mechanical regulators that wire is positive and you are ( or whoever is ) on risk to cause a short there plug in it on a grounded prong.

Thats my option just to keep a clean view on back on alt, without any wire bolted around to feed that ground

I have a 1976 vintage, 78 amps, two fields, externally regulated alternator on my 68 Coronet. I simply grounded out one of the field connections. It works fine. I didn't remove the second field connection because one of these days I'm going to rewire so I can use both fields.
