I have a 2500HD with a rigrunner installed that continues to shut off due to the alternator pushing out more than 15 volts. Its a factory 2 battery install wired in parallel without an isolator.
I have a few USB adapters, dashcam, and a kenwood 281 wired into the rigrunner. Overall load at rest is less than 1 amp. I don't see how the load from the rigrunner would cause the alternator to push out the high voltage.
One battery is less than a few weeks old, the other has been tested after deep charging for a night. I'm at a loss - any ideas why the alternator pushes out the 15-15.2V? Could i put a voltage regulator between the battery and rigrunner? Any help is appreciated.
