Can't find the convertor book says under clothes closet but not there . switch to 110 outside sorce thumps but batteries are dead and they are new, any help Thanks Jimmy
  • Yes THUMP is ATS working. the on /off on dash could be bad I never use it but could be bad, can't fing convertor. Thanks Jimmy
  • First find MAIN DC Dist Panel......has all the 'house' DC Individual circuit Fuses
    Close by/behind it/next to it would be the converter

    Question.....
    Whenever I read 'new batteries' I have to ask
    Did you mark battery cables prior to removal, if not did you trace battery cables prior to connecting to new battery.

    If connected backwards.......'reverse polarity' fuses (30A or larger on converter) blow to protect converter electronics
    If blown ---no DC from battery OR from converter when on AC
  • Transfer switch. Possibly mounted to the back of power distribution panel.
    Check for circuit breaker adjacent to the batteries.
    possibly battery disconnect in disconnected mode or bad. Try turning them off then back on.

    What thumps?


    Perhaps he is hearing the ATS (Automatic Transfer Switch) latch in-- just a guess.

    Should be able to track down the source of the "thump".
