A buddy's 2003 Flagstaff Pup with a WFCO 9245 converter is acting weird. The converter is working and there is battery voltage to the converter. It's not charging the battery, nor will anything run on battery only. All works ok on shore power. Seems like something is open in the converter between the battery fuse and the converter output. Its just weird as there is battery power to the fuse, but no converter output on the other side of the fuse. I guess the converter card is fried?? BTW, were camping right now so we're under the gun..

There are two 40A fuses in the convertor. Of they blow, the situation you describe will occur. The can blow if you plug in RV and battery is very low/dead or if the battery is connected in reverse. In most cases they are an orange/yellow. Check both

I would check underneath trailer at front near battery for a re-setable mini-breaker and push black button.......
Thanks. He has battery at the converter, so the resettable breaker is ok.

Where are those fuses? He has a single 20 amp in the fuse block for the battery feed. Thats where I've been getting the 12v from the battery but nothing on the converter side of the fuse even though the converter seems to be working. There is another fuse labeled "main" that's ok. If I pull that one, all goes dead....I think thats the converter feed to the fuse block.

Sorry Herk, there aren't any 40 amp fuses. Go with the pix...Right to left is battery fuse (battery to converter), next is water pump, lights, accessory then converter fuse (converter to that printed circuit card-fuse block)

Drawing looks like it, but the door says (?)245.Im gonna look at your link to see if its different than what I found.

Yep, you're right, it does say 8712(25) on the circuit board.

RESOLUTION!! Today I had a chance to figure out my buddy's electrical problem. I had VOLTAGE from the battery to the fuse board. And voltage from the converter to the fuse board. But nothing would run on the battery. DUH, I should have thought of corrosion. There can be potential thru corrosion, but as soon as LOAD is applied, the high resistance of the corrosion causes a high voltage drop and thus nothing works. DUH. So I traced the wiring back to the battery and there it was....a 20 amp fuse shoved beside the battery near the bottom and all corroded. Neither my buddy or I pulled the excess wire out of the battery box or we would have seen it. I replaced the fuse holder and added a battery disconnect for him.
Just a refresher, just because one has 12 v on a circuit, doesn't mean current can flow.
Thanks for everyone's help.

Add to that, bad crimps in connectors at the factory. No heat from a nice furnace taught us that one. Cleaned and recrimped all connections I could find.
