Sounds like the alt is not charging. Chech the plug on the side of the alt for 12V, it needs it to turn on the voltage reg.

He means check the input voltage on the side plug with your volt meter.Although it may just be a bad alt. I've known people who went through 3 different ones before they got a good one.
