The yel/blk wire is the sensing wire here is the alternator wiring diagrams so you can see how the system works. Yours is a three wire sensor. Check out the images (below). Please let us know what happens.

This isn't how my alternator is set up, mine has the wire that goes to the battery and a plug with two wires ran out of it. I need to know what each wire that comes from the plug are one is the sensing and the other is the exciter on the diagram shown the exciter is the ground wire.
