Question about something in the Coach Battery Box

:S

It is one of 2 things OR the same thing.
1. It is the battery disconnect solenoid(not likely due to the 2 large battery cables)
2. It is the Solenoid that closes to charge BOTH chassis and coach battery banks (99% correct)
3. It is the SAME solenoid that is the emergency start AND the dual charge solenoid. A LOT of Motorhomes use the same solenoid for this purpose. The BAD news is, IF it IS a Emergency start solenoid, it is not HEAVY(Large) enough for that job. THAT solenoid is rated at no more than 100 amps draw thru it. It probably does the job, but an emergency start solenoid really needs to be either a 150 or 200 amp rated solenoid, but few older motorhome makers put those in.
4. The fact that you have 2 large heavy battery cables point to a emergency start solenoid that probably does double duty as a charge solenoid also. Doug

It could be a four post version of this.Battery disconnect

Sorry. I rushed the first post. Motorhome is a 2007 Coachmen 21QB. I'm not sure where the yellow wires go. The motorhome has an emergency chassis start button so I assume one of the big red ones heads north towards the engine bay.

There's a Coach Battery On/Off rocker that's a momentary switch so a relay would make sense.

I was hoping someone might just say "Oh yeah, that's the Fribbitz Valve!" :)

I'll press some buttons and listen.
I need to clean it out too.

I have a 2007 Georgie Boy 24DB and that continuous solenoid serves two functions. One the emergency override and when the engine is running connects the engine battery to the coach batteries to charge them. Coachman owned Georgie Boy (my power center says coachman on it)

A better (larger) picture would help.

Oh yeah, that's the Fribbitz Valve. They are new for model year 2006 and later. Keeps the Fribbitz from overloading the Thingamajig circuit.

Not a shunt, Too small for Aux. start solenoid. I bet it's a battery disconnect?

Yep.

Bought the rig used.
As soon as the 12* weather goes away, some major sprucing is in order.
