I have no power on the house battery charger on my 1989

Customer Question
Monaco crown royale. I...
I have no power on the house battery charger on my 1989 Monaco crown royale. I cannot find a fuse or breaker anywhere. There is just no voltage on the house charging battery cables. The coach is new to me (only owned for approx 2 wks) The switching circuit seems to work ok (shore line power/generator) but I cannot get power to charge house batteries. Any ideas? Thanks. Converter seems to be working but just no charging capability.

Most likely you have an inverter and not a power converter. IF that is the case look for a large fuse bolted to the frame between the inverter and battery. Make sure you have continuity through the fuse, if that fuse is blown then the batteries will not charge. IT is a large fuse, probably a 200-400 amp fuse, one cable from the inverter will get bolted down to one side of the fuse and the other side is bolted down going to the batteries.

I might also check your battery cables make sure everything is clean and tight, try and power the inverter down and then back on to reset it. IF the fuse is good and the batteries are not charging I suspect an internal problem with the inverter.

Hope this helps out, if you still need more help please get me the make and model of the inverter.

IF you are satisfied with my efforts please feel free to select a STAR rating on the page...

Cleaned all terminals. Book on the coach refers to the charging system as a converter. Sounds like the problem could be a fuse however. Problem now is just finding a fuse.
RV Mechanic: Robert, RV Mechanic replied 8 months ago

Follow the cable from the inverter and going back from the batteries, it is normally mounted on a frame rail, could be in the engine access area or near the batteries..... On some older units they stuck it under the engine access panel inside, mounted over the engine. Following the cables you should be able to find it.

IF you still need more help please get me the make and model of the inverter.
