    11984 C30. I accidentally left lights and instruments on (yeah, I know) for a week. My batteries were dead, which I replaced since they were old, anyway. But my shore power does not work. Perhaps I fried something. Any ideas?

    Lots of ideas. Maybe we should check:
    1. Switches
    2. Plug
    3. Wires
    4. Marina powered up
    5. Bill paid
    6. Boat circuit breaker.
    To name 6. Hard to say with so little information.

    Maybe your marina flipped the breaker for shore power to hopefully eventually make the lights go out. It would have been nice to contact you. But .....

    The boating gods frown on killing batteries. They took revenge as a teaching moment?

    POSSIBLE solution..

    Do you have an inverter? Some inverter/chargers CUT-OUT unless they have a battery with at least (say) 8 Volts in order to avoid frying the boards in the inverter/charger.

    If that's the case, you have to put a jumper cable (or a jump starter) on the batteries; and, they inverter may come back to life.

    It's also possible that you fried the inverter charger if it has no protections.

    My charger/inverter cuts off with low voltage. It will power back on, but it gives an alarm and cuts back off. Once the batteries are charged, it powers up fine. If I connect to shore power, it will charge the batteries.

    Does your boat have a breaker near the shore power inlet?

    My Hunter had one way in the back of the aft berth. Just a single switch or breaker that killed power to the distribution panel.

    Is the main distribution panel breaker on? Or maybe tripped?

    My outlets are through GFI outlets which sometimes trip off, and then I don’t have power in the outlets.

    I think we need more info.
