Bigfoot 17 Electrical Problem AC yes DC no??

[hoppy1962]

I have a 1990 Bigfoot 17.

The AC is working but not the DC.

I get 12V DC from the fuse panel on the Power Converter. But no where else.

I figure that I must have a bad ground somewhere.

Anybody know where to look for a bad ground ???

Look for a fuse from the battery maybe under battery box or in and around hitch area.

My 94 Bigfoot has an inline fuse between the battery and panel. It's located under the dinette seat along the front bulkhead an it is a 30 amp glass fuse in a black fuse holder.

Found the 30 amp battery fuse. Tested it and the other ones on the power converter. Their all good and still no DC.

Would it not be simpler/easier to just run another ground wire rather than to look for the one that might not be good?

Fill an old coffee can with dirt and place it under the bed and you will have a new ground.

Look for the ground wire from the converter to the frame. Could have corroded off.

Did you put a tester on the wire going to the fuse? Any power to it?

Not sure about the older Bigfoots but some trailers (mine included) have two inline fuses - on right off the battery outside and another inside the house.

What brand and model is your power converter?

I went through the trailer testing all the ground wires with an Ohm meter and a Pin.
They all tested good. So I plugged in the trailer to my AC wall outlet and abracadabra! I have DC again. Don't know why. Probably wiggled a loose wire tight again. Thanks everybody for all your help.

Humm are you sure you actually have DC power again? if your plugged into a 110 wall outlet your getting your power via the wall outlet and converter not the battery. If your lights do not work when not plugged into the wall outlet you still have a DC power issue.

try disconnecting the battery posts, plug in the converter to 110 ac and test with a multimeter the wires at the battery while it's disconnected and see if power is getting to there

Pull your battery out and take it to your local auto parts store. Have them do a load test on it (it's usually a free service.) I'll bet your battery is shot and needs to be replaced.
