Somewhat mysterious 12V problem.

After taking our Scamp13 out of winter storage, when plugged in and connected to the TV all electrical seemed fine. However, when disconnected from the car I lost 12V. I thought it must be the converter so I tested battery voltage with the converter unplugged: 12.75V, when plugged in it went to 13.5 indicating a working converter.  All breakers are on and all fuses test good. It was working when I parked it.

Any ideas what i"m missing?

mysterious 12V problem.

Do you get it back when you plug back into the tow vehicle? The breakers are only for the 120 VAC so start following the voltage on the 12 VDC wires and fuses. Please let us now what you find. The  battery and converter both sound like they are connected to each other, but not to the Scamp lights etc. It's too new to be having a problem. BTW:  What is not working? Have you tried everything? Do not forget to check the ground wire of the circuits also.

Yes it comes back when I plug

Yes it comes back when I plug back to the car. There is a row of 12V fuses next to the 120 breakers which all have the DC voltage to them and none are blown. I feel like I'm missing something obviouys; as soon as the sun comes up I'll recheck everything.

I'm lost

If all of the fuses have power on both sides, pumps and lightsshould work unless the ground is open.

Good luck.

Need a fuse tester...fuses

Need a fuse tester...fuses can look good but be blown where you can't see it.

If not now, when?
