I just got me a classB motor home based on a Dodge van. It was cheap so I knew there were issues. I called a friend up who helped me get fuel going. But then he check the battery and found it was not charging at all. Not being a Dodge man it took him a while but finally figured out it was an aluminum or something box on the firewall. Pulled the wire of from the alternator and ran it to the battery and the battery was charging. So what I know is that the box has something to do with Onan generator. The deep cycle battery between the engine and generator is completely dead. That battery is what is used to start the generator so I have no idea about the generator.
Anybody have clue what the problem is? Can I drive it with the wire going staight to the battery?

As long as the alt is charging the eng battery, u should be fine. The box on the firewall may be a voltage regulator from the Tck alt to the genny battery and Tck battery. By by-passing that, and going directly from the he alt to the bat, he made sure the Tck bat gets the charge. U could run another from the Tck bat or the alt to the genny bat and charge them both till u can get a new genny bat, or lv the genny bat alone till u can buy a new and then run the wire to that new bat. I don't understand why the genny bat doesn't recharge its own bat, but I'm not an rv mech either.

Voltage regulator is next to it. When he could not figure out what it was he ask if there was an Onan. Then he said it had something to do with the Onan. I'll take a picture today and post it. I am driving it today so we will see if it makes it without burning up.

Could that other box be a voltage regulator for the genny? Not looking at the Tck and the wiring of it and where is leads from and to, it's hard to say what that box is. But from ur discription, it sounds like a separate regulator for the genny. It could be a regulator from the genny to the Tcks charging system too.

I think it allows the gen battery to charge but not pull from the gen battery like a one way door.
