I have a 2000 Volvo with detroit. Is there anyway to disable the low voltage disconnect on this truck? It kicks in before the APU has a chance to fire up. It starts alarming just when the Apu is starting it's warmup process. My alternator died and it cut off my headlights and dash cluster preventing me from limping to the dealership. 2nd issue I have is the boost sensor is tossing a code mid 128 pid102 fmi3. Says it has an electrical fault.
