| My 2010 Case IH Quadtrack voltage has been erratic. It goes down to 12 volts than can go back to 14..2volts. I assume alternator is ok because when the display and also battery post are testing 12v the alternator says 14.2volts. Cleaned all the grounds and main strap ground from engine to frame and still the same. Also when voltage is reading low like 12v when i turn all lights on it drops to 11.4volts but it only drop .2voltage when display is 14volts or more. | |
