Truck camper

I hooked up to 30 amp shore power, all the lights in the camper went dim and then dimmer. Also the heater would not heat, everything else, plugs and heater/ ac worked fine. Not sure what the problem is.
  • Did you check the park 30 amp power supply? Polarity? Voltage? Prior to plugging in?
    Is this a new TC? Has all this stuff worked somewhere else? In your driveway? Other parks?
  • All of these things you mention are 12v powered. Look into you power convertor, battery switch and batteries.

    If you have an inverter, turn it off.
  • Fuse or breaker connecting your 12v converter either to the batteries, or to the 120 volt supply.
  • Did the lights go completely out? You said heater would not heat but then said heater/ac worked fine?
  • Check the fuses to and from the 12v converter/power supply
  • There should be 1 or 2 30 AMP auto fuses in the 12 volt fuse panel I would check those first, and when mine were bad they tested okay but for some reason didn't work right when there was a 12 volt load on them after I replaced them everything was fine
