I would first have the alt output checked when it is showing low voltage. Also, if it is good, start looking for bad grounds, make sure the ground to the engine block is clean and tight.

Let me know what you find. NOTE: If you have it checked when it is showing low voltage, you will know if the alt is doing its job or there is a different problem.

Let me know what you find.

@shad722005. Did you ever find out what the problem was with your volt gauge? I'm having the same problem now.
