Sparky242 Posted September 6, 2023 Report Share Posted September 6, 2023 I think it would be the same as any auto assuming it's a 12-volt system. If it is a 12-volt system the battery's if charged should be at 13.2 volts You will need a multimeter set to DC volts, with the coach running check the voltage at the coach battery's They should read somewhere between 13.5 to 14.2 volts if itis charging. Turn on the headlights and blower motor, the voltage should stay in the 13.5 to 14.2 volts range. If the voltage falls off, I would pull the alternator of and have it checked at an auto parts store Quote 2000 Volvo VNL 610 2011 Cedar Creek 36RE Link to comment Share on other sites More sharing options...
