You can take it to an auto parts store and they will mount it on their testing machine to tell you if it is working correctly. My alternators have all been three or one wire. Never heard of a two wire before. Do you have the battery wire hooked up correctly? Jag

Does one of the smaller wires go to a power source that turns on and off with the battery?

I see the problem. The red wire comming out plastic plug should hook to the battery not to ground. You may just be able to hook it to the main red wire on the back of the alt. The black wire should be hooked throu a warning lamp than to the ignition switch at the run term.

So the red coming out of the plug then should be conected to the top post, and the other to the bottom?

The red wire comming out of the plastic connector should be hooked to the lug on the back were the other red wire is.

O.k. So both red wires together on the same stud, and nothing on the bottom. Right?

I am just making sure I understand
