A member with a 2002 Holiday Rambler Atlantis reported a sudden total loss of power after a year on the same shore hookup. Early replies focused on basic isolation: confirm whether all outlets were dead, check for a tripped GFCI, verify the pedestal and breaker on both the park and RV side, and determine whether the issue affected only 120V outlets or also 12V systems like fridge controls and interior lights.

A member with a 2002 Holiday Rambler Atlantis reported a sudden total loss of power after a year on the same shore hookup. Early replies focused on basic isolation: confirm whether all outlets were dead, check for a tripped GFCI, verify the pedestal and breaker on both the park and RV side, and determine whether the issue affected only 120V outlets or also 12V systems like fridge controls and interior lights. As details came in, the key finding was that both the chassis and house batteries were dead, which shifted the diagnosis toward a failed or non-charging 12V system, a converter/charger problem, or loss of incoming AC power that had been masking weak batteries.
The strongest consensus was to stop assuming the pedestal was good just because it had been checked and instead verify power step by step with a meter: pedestal, shore cord, RV breaker box, battery voltage, and converter/charger output. Several experienced members noted that loss of 12V can make the fridge, HVAC controls, and other systems appear completely dead, even when wall outlets should be a separate clue. Other plausible failure points mentioned were a worn pedestal receptacle, bad park breaker, loose shore cord or breaker-box connections, inverter breakers, automatic transfer switch or transfer relay failure, and a reverse polarity transfer switch. One member shared a successful repair by replacing that switch near the bed and fuse area.
The practical path forward was clear: recharge the batteries first, then retest the coach systems, start the engine if possible to restore some 12V support, and use the multimeter to confirm where power stops. If battery charging does not restore function, members recommended tracing the shore cord to the distribution panel, checking converter/charger operation, and considering a mobile RV tech if electrical troubleshooting exceeds the owner's comfort level. The most useful takeaway was that the failure may involve both a dead battery bank and an AC charging issue, not just one simple breaker problem.
