This is embarrassing: Magnatek failure?

O.K., the plot thickens. After reading all your responses, I checked all the 110v breakers in line with my circuits, I used my non-contact voltage tester and worked my way back from the TC to the GFCI plug. No circuit. Tried to reset the reset button and it won't stay in. So, I hooked up another 80 feet of extension cord and ran it to our attached garage. This should work, right? Wrong. THAT GFCI was also non-responsive. Two in a row? I found a closer plug inside my train room and tested that plug. Works fine. Ran 50' of cord out the 12' rollup to the camper and plugged in the 30amp cord. Bingo! The soft, telltale hum of my old Magnatec was detected. I then worked my way thru the Box testing every single circuit. All work fine and my 110v night light was glowing nicely. All the new upscale bulbs were good.
The battery is at 12.6 volts now and it's clear that the 2amp charger had no juice and the charge was slowly going down due to the parasitic drag from safety appliances.. So, the question is: shouldn't the 12v circuits work with 12.6 v.even when not being plugged into the 30amp 110vAC?
Thanks ever so much for your kind attention. There is not an RV forum on the planet that has as much knowledge as youse guys possess.
I think Lawrence Welk, the king of malaprops, talking to his band summed up the day as well as anyone:
"My poys, der are good days and der are bad days, and dis is one of dem."

Yes the 12vdc circuits should work.

Measure at the magnetek like I pointed out.


The following is in reference to your shore/gfi issue only, nothing to do with 12vdc for now.

Your camper has a ground fault somewhere in the 110 circuit that is tripping those GFI's.... Not good. Plugging into a non GFI protected could provide a shock in the camper or touching the outside while standing on the ground, so be careful.

Is you fridge a 3 way by any chance?


Even if it is not unplug the shore power inside the outside compartment and retry the GFI shore power outlet.
