Hi all,
Just got back from a cruise and now the master ON switch for my AC Panel instantly flips closed. All the subsequent breakers, charger, outlets, and water heater, are all OFF. I have a Smart Plug and checked the wire connections on the socket and they seem fine. I tried a resistance test with the multimeter of the socket side of the shore power cable but found nothing conclusive. Admittedly, I don't know what I'm doing with the multimeter here.
Pulling the panel off was also inconclusive, as the connections look original and not in terrible shape. The shore power worked fine at the marina we stayed at last night. Somewhere in the 5 hour motor home, something died or changed. My first instinct was water getting in the shore power cord, but it's been sitting in the sun with the same issues.
Any thoughts as to what could be causing the short? Perhaps the breaker itself is old and dead?
