If you are seeing 13.5v and above, it sounds like your alternator is all good.

Good to know, didn't think about testing at the jumper points. New battery and ctek 7002 ready to go.
I am think due to me lack of long drives (about 2-3miles per day) and lack of frequency driving the X, the ctek should help out.
Thanks again!
