Battery switch wiring on my 96 Bounder?

Around 1996 I think the wiring for disconnects changed to allow the start position to close the disconnects. This may have also been the time when the converter charged the chassis battery. This is just experience, as you can spend days trying to trace the wiring semantics and actual wiring. There seems to be changes that were made on the floor, that did not get documented, but were necessary for production reasons.

Thanks guys I’ll check it out tomorrow but I checked my dads 08 Bounder and if I turn his main switch off and try to start it, It too starts up. Also, my disconnect must work as when the main is off my camera and lights are off. I have a sneaking suspicion my 6v batteries could be shot and everything is running off the Main because of that.

You can not always go by what other year Bounders do electrically. The RV Customs Products BCC has been in a state of evolution since its inception. As an example, in mid 1995 the BCC was redesigned so the chassis battery will charge when plugged in to shore power (CB 200 Rev. C). Also some where in its evolution, the ignition circuit was removed from the main relay due to the engine dying, while under way, if the relay failed. Safety issue. Then a feature was added to close the relays if the ignition key was turned on or you plugged into shore power.
So now all you need is a responder to tell you how his/her Provost works. GRIN

My '94 Bounder the 'Main' operated the House circuits and the 'Aux' operated the chassis circuits. Each system had it's own 'power on, power off' top hat type relay and both were inside the BCC. Those relays are easily taken apart and the contacts cleaned and polished. As far as knowing exactly what the Main and Aux solenoids powered up never really mattered. I'd just press the Main and Aux when getting ready to leave, and go.

The alternator output was controlled by the BCC, and it would first charge the chassis battery after starting, than 2 minutes (or longer) later it would close a relay and also charge the house batteries...if they weren't too low. Low like if they were bad or I had been dry camping. In that case, shore power would charge them up at the next RV park. But shore power would not charge the chassis batts, had to add a Schmacher charger for that.

BTW, the '94 I use to own is a diesel and I have schematics I found online that show much of the BCC wiring and setup. PM me if you want copies of the PDFs.

My blog (address in sig), has a '94 Bounder section you might be interesting in reading...

I do not know why, but this has worked on numerous MHs. Yes, the OP is not clear as to what the problem is. Seems to be saying it works, but does not work?

Well we had a 94 Bounder. Motor/ignition only worked with Main on. I had the Main disconnect solenoid fail and had to replace that. With no shore power and AUX off no lights or 12v to anything not running off ignition. Not sure off the purpose of the Main disconnect on his HM if the engine starts when it's off. Almost sounds like someone has made a few mods, maybe to work around a bad disconnect solenoid.

Hey guys, with main off my camera monitor and house lights don’t work. When flipped on they work. Motor runs no matter what. With main off and aux on nothing happens. I just don’t understand how it all works. Thanks

cm2785,

Not plugged into shore power, the chassis motor should not start with main battery off. Interior lights should be on the aux (house) batteries. From the factory the back up camera is on the ignition relay. Wiring print is on the back side of the BCC cover. Under the hood.
For better guidance goto rvforums.net/ tech talk and ask "Just Lou" for help. He is the RV Customs Products BCC guru.

I'm a little confused about when they work and when they don't. It started and drove then you hit the 'main' switch? Shouldn't start with main disconnected/off. Then you connected AUX batteries and they didn't work. Was main still connected, was engine still running? Maybe you could explain it again.

Engine alt should charge all batteries. If lights only work when engine is running it sounds like aux batteries may be dead. Have you plugged into shore power to see if lights work? Check voltage of AUX batteries.
