no power to hyd jacks control panel

I have a 2013 fusion 375. I needed to move it and there was no power at the control panel. I have checked fuses and breakers and appear to be good. Any other ideas?

I'm thinking I have a bad converter. Any thoughts?
    Measure across battery terminals for acceptable 13+ VDC when converter is powered. You might check to see if you have a manual resettable circuit breaker on a battery wire that connects to the converter.
  • Is the AC power to the converter good? A good 110 volts. I know you said you hear a hum from the converter.

    I don't have any specifics to offer but

    1. is the battery in good shape and charged?
    2. are all connections made up on the battery? sometimes more than one wire has to go on a battery terminal. maybe a connector came off?
    3. does some other condition have to be met before the jacks will operate? if so you already know what they are, but if a sensor that confirms something isn't working, then the jacks will think it wasn't met
