AC works...

[bpike]

but not the DC. Battery is good. Wiring is correct. Think the fuse switch is bad. Any other idears?

What's not working?

You said the wiring is correct and battery is good. Is the black wire at the battery hooked up to the plus or minus terminal? Unlike popular theory, the black wire goes to the positive term. and the white goes to negative.
Of course if you have red and black, then throw that last line out.


Please supply more info.

Just like I said. All the wiring is wired correctly and I bought a new battery that works. However...NOTHING will run straight off the battery (DC). Everything will work when I'm plugged in (AC).
I've gone to the convertor box and switched over from battery to convertor when I'm running AC and vice versa when running DC.

So leads me to my question. Since the wiring is all correct and the battery is new and the convertor switch is switched...what else would cause the DC to not operate?

There have to be fuses.

There is usally a fuse in-line on the positive wire somewhere near the battery.  There is probably a fuse on, in, or near the converter.

The fuse(s) may look good but still be bad.

There are just about as many electrical systems out there as there are campers. You will need to let us know what year and model camper you have in order to assist you better.

From what you have told us, so far, I can only surmise that it could be a bad ground or a bad battery cable (assuming that the fuse is OK, if it has one). We have had a few members that have found that the wires from the battery were separated inside the insulation of the wire. That's harder to find then you might imagine. The wire may test OK with an OHM meter but when you put a load on it, it fails. I would suggest running a jumper wire from the battery to the converter. Do the positive side first. If you still have nothing, try the neg side but be sure to run another jumper from the converter to the frame.

Some campers have other switches and systems that may need to be checked.

1.  Wiring is correct for your camper (black to +, white to -, or whatever)
2.  All outlets work when plugged to 110v, including 12V outlets and lights and 110V outlets
3.  But nothing works when the 110V shore power is disconnected.
 
I have to agree with Wavery.  There is a disconnect between your battery and the converter.  It will take some time spent with a test light or multimeter to find it.  But look for the obvious first:  broken wire, corroded/dirty connection.  Then start tracing wires.
 
Good luck.  Let us know how you make out.
