Make sure the smaller wire of the two from the harness has 12V switched. There should be a large wire, 12V constant, and a small wire 12V switched with the ignition. A break or short with that switched wire would cause an alt to not charge.

Yep, Voltmeter is your friend.
There should be a large red wire on the back of the alternator that goes thru the frame to the battery compartment, it provides charging current to the battery. Ring it out and make sure its intact

Check the starter wire. They can go in pairs and I would hate to see you stuck on the side of the road some day as a result.
