House Batteries

House Batteries
HB on my Winnebago 2007 does not charge while driving.
The switch wire (LR) to the solenoid does not have 12 v.
If I apply 12 v to the (LR) wire then the house batteries will
charges.
I have check all fuses and breakers all are good.
Where does this (LR) get it's 12 v from?
If I could find that I think my problem would be fixed.

I have the wiring diagram that where the picture came from.
The (LR) wire goes to a (wire ASM-IP Main socket) and stops.

I need to know where the 12 v should come from, and the wiring don't show that.

If you can't locate where the is, I would think any keyed 12 volt source would work to energize the solenoid, even if you need to add one.

Yes any 12v will close the relay, but I just want it close when I driving.

That is the reason I trying to find the source 12 v.

True, that is why I said any "Keyed" source would work. When would you have the ignition key on if the engine was not running?

It should come from the ON position of the ignition switch, but few things connect directly to the switch itself. Your coach probably has multiple places that are "hot" only when the key is on & engine running. Hook it to any of them.
