using my "Torque" app on my android the current voltage at the OBDII port is reading 12.4-12.9, varying with headlights, defrost, wipers, etc. At the gauge it is also reading lower then usual (being right about dead center) it is now leaning towards the "-" on the pictured batt. The alt had 132k miles on it and is the orig. I swapped it to the one that came on the used motor it was good reading 12.8-13.1 volts then started doing the same thing.
Time for a new alt?
