Help No power at dashboard won't start

So it all started when I plugged in the wrong shore power plug. 30a 120/240, not a 120 only. This shorted the outlet for the fridge and might have fried the microwave. Now I have no power to dash. Nothing happens when I put the key in the ignition.

    The only effect on the 12 VDC systems would be that you likely blew out your converter or inverter/charger so the batteries may be dead.

    Start by checking voltage at both chassis and house batteries
    +1

    Then start checking fuses if the batteries have 12.2+ volts.

    I am guessing your converter is fried and not charging. Sadly this is something we warn and warn and warn and warn and still we get told it happens.

    Oh and as you spend big bucks to get things working again
    Consider a Progressive Industries HW-30C about 200 for the unit and about 80 for the remote at multiple retailers.
  • If the problem was due to somone else they may be liable. 30A RV plugs which are labeled 120V are NOT physically compatible with any 240V plug. But some have managed to force the RV plug into a 30A 240V 3 wire dryer plug which is similar and let the smoke out.

  • A voltmeter is your friend. Anything AC that was turned on or in standby could be toast. And apparently AC got into your DC systems as well.

    I'd check the batteries, turn off the charger, fix the AC and then the DC. The fortunate ones that do this have blown fuses and tripped CBs but for many it's big $$$.

    And the last fix should be to install a EMS like the PI HW30 to protect the rig.
  • time to get the meter out,start at the main fuse .follow the power till it ain,t there. you could have toasted a hole bunch.
