I plug my Tab 400 into shore power at home. I turn the battery switch off. Now I have no power plugged into shore power. I checked and have power all the way to the plug. I turn the battery back on and have full power. Any ideas why I no longer have power on the trailer while hooked to shore power? Checked switches and breakers and like I said, works fine on battery power.

    First guess, the WFCO Power Center internal convertor has failed.
    Assuming 'no power' means no lights, etc but the 120VAC outlets are working.


    The convertor produces 12VDC for battery charging and cabin 12V stuff like the lights,etc.
    When on Shore Power and with the Battery cut-off switch 'On Battery' the cabin 12VDC stuff gets there power from the battery if the convertor has failed.

    There are some DIY troubleshooting guides for checking if the covertor is functional, a voltmeter is required.

    Got the multimeter out and found a bad cord. All good now. Thank you for replying.

    @s810 where did you find the bad line? Was it a manufacturer issue- was the cord failing due to vibration going down the road?
