Normal Alternator Voltage?
Normal Alternator Voltage? I've noticed since my swap (2006 5.3) the running voltage seems to sit right at 13.5v regardless how I drive, or what I do. The lowest has been 13.4v, the highest 13.6v. What gives is this normal?
FYI- I eliminated the battery module which was taped to the Bat Neg cable. I rearranged the pinouts at the ECM though(It's been a while..) This shouldn't cause this....?

I rarely see a large voltage fluctuation in my Thunderbird through HP Tuners or my multimeter. The only time I did see large changes was after some wires got cut in a wreck I had or with my old electric fan that was going bad.
On the opposite side, I do get a swing in my 02 TA, but everyone thinks the alternators are too small and the grounds suck on those cars anyway. I agree and will soon be upgrading.
