House batteries not charging

2007 Winnebago Access 31C on a 2007 Chevy Workhorse Chassis 6.0L engine
2 6 volt U.S. house batteries 1 Sears Platinum Engine battery

Ok so I had an issue of the Aux Start switch not working and the house batteries not charging.
No Problem, got it figured out that the solenoid was bad as when I pressed the AUX START = no click
Changed it out for a new one.......NOW comes the bad part.....
Start engine =Fine
Check alternator at engine =Fine
Check AUX Start = Fine, Solenoid clicks like it should
Check house batteries = NOT fine, no connection from Alternator to house batteries

So while the engine is running I can push the AUX START and the house batteries jump to 14.3 volts........ perfect!
This means they connect if I need to boost the starting aspect.

Let go of the switch and house batteries are now disconnected....It's (the solenoid) supposed to pickup the fact that "Engine is on" and is supposed to connect the house batteries to charge them while driving....this does NOT happen.

I checked the AUX switch it's fine. I installed a new solenoid and I know it works as I press the AUX button and batteries all connect.

The issue that I'm pulling my hair out is that there is a fuse or something from the AUX switch to the solenoid that is preventing the connection to the solenoid. Winnebago can't help me they say check the fuse but have no idea where that fuse is.

I checked both fuse boxes and all fuses are good.

Winnebago then says follow the wire from the switch and see where is goes.

NO F*****G way I'm taking the entire front end, seats, flooring out etc. to follow a wire.

So has anyone here had this issue you can give me a clue what fuse Winnebago uses in the Chevrolet Chassis?
Or, do you have any idea where the wires from the AUX switch go?

I'm really not in the mood for bunch of possible things to check as I think I've got it narrowed down.

If you KNOW great !!!! if your guessing.....Thanks anyway.

Just an idea, Run a temporary fused jumper wire and see if it now works. If so cut original loose at both ends and run a new circuit. With rvs there is no telling where the original is fun and fused. It seems as everyone on the assembly line did whatever they wanted in most cases. Cutting a circuit out and running a new wire is preferable to tearing into a harness,in fact being the prefered repair in the auto industry. Does Not create new problems while fixing one.

I have 2 separate solenoids. 1 for boost and 1 for charging.

Oh, never mind, I don't know your system.

Just exactly what I was going to say.

I have a AUX solenoid down the back to boost, then a second solenoid under the hood that charges the house batteries from the alternator.

If you have one solenoid still not working.

Figured it out. Was a dead 12 volt (key ON) wire. Wired in a new line with fuse everything works fine.
