Clicking with Shore Power

Hello,

I just purchased a used 97 Jayco trailer. Started cleaning stuff up and getting things figured out at home last weekend. Saturday afternoon I wired up a 30amp 110 volt recepticale to plug it into shore power. I also plumbed the propane back up. I did a quick check Sat afternoon to see if the furnace and AC worked and checked most of the lights. Everything seemed good. At this point I new the battery was dead. I had previously tried to charge the battery that was on it but it would not take a charge.

Sunday when I walked into it I heard a clicking sound coming for what I assume it the converter. When I unplugged the shore power the clicking noise would slowly die out.

I did a little research online and read that the dead battery may be the problem. I purchased a new battery, fully charged it and installed it last night. Plugged it back into shore power and the clicking continued.

I am new to all this and am looking for any advice on where I should look next.

Thanks,
Brian

    Sounds like a capacitor is failing.
    Make and model of converter?


    Not sure on the make/ model of the converter. I will check when I get home from work this afternoon.
    Capacitor would make since. It does sound similar to the noice I have heard from other failing capacitors. It would also makes since how the noise lessens as the capacitor discharges.

    Voltage is actually suppose to be 120 volts AC from utility.
    Then premises installation causes voltage drop.

    The refrigerator and furnace ignition clicks.

    What would you use? Tens of thousands of RVs have 30a 110vac service.

    Is it possible that your rig has an Electrical Management System installed somewhere inside?

    I have one in my trailer and if the power source is unable to provide full current to the load (mine was routed through an electronic timer switch to power the fridge overnight before leaving home) then the contactor inside will click furiously to try to shed the load from the power as the input voltage drops.

    I now use a dedicated circuit for the trailer when at home though it is still limited to 20A.

    There is no reason not to run AC on a 30 amp shore power setup.
    Problems develop with low voltage or when actual circuit is a 15/20 amp receptacle is used with an adapter.
