DC side issue Coach Batts not charging
When I purchased the coach was told batts were good. I had AC power plugged in but no DC. Control panel didn't give lights, no genset crank and so on. I figured I'd do the most obvious things first. S...

It would also help if I understood fully the battery mode switches also mom/duel I get the batt condition button with gauge. That's obvious but if I don't have one of the switches like Aux in the right position would that keep them from charging? I've got all the books and paperwork for all the components on this rig with the exception of anything from Winnebago instructing me on how anything works like what switches are for what. It's a guessing game
On your year Winne. The Dual/MOM functions like this
On DUAL when you push it, it stays locked in. This closes ANOTHER charge solenoid (that silver one like you purchased), that engages both battery banks to charge while driving down the road. If you leave the Dual switch engaged and you turn the Ignition key OFF, then that solenoid opens. Most leave this switch on all the time.
The DUAL side uses Chassis battery power to close the solenoid when the Ign key is ON.
On MOM (momentary,called emergency start on other RV's), which is spring loaded and will pop back when you release it, pushing this side and holding it, will close that silver solenoid to use the Coach Batteries to jump start the chassis engine if the chassis batteries are low or dead. The MOM side uses the coach batteries to engage the charge solenoid.
As you found out, you have a broken Intellitec Disconnect relay and it operates completely different from a solenoid that uses 12 volt to close the solenoid. The main feature of the Intellitec is, it is called a "latching relay", which means it does NOT consume any 12 volt power once engaged or disconnected. Doug
