Question ref. to my 2015 Thor ACE 30.2

Hi. looking for help with my 2015 Thor ACE 30.2

I serviced my house batteries and cleaned contacts. Since I purchased in 2014 my house batteries would only charge while hooked up to the service line or if generator was running. Attempting to find out if it has a battery isolator and its location.
Thanks in advance...

Follow the cables from the house batteries. They should go to the isolator or a relay.

Most use a relay that latches these days. It might be bad.

Push the battery emergency switch on and off, while listening for a solenoid to clunk.

That solenoid, a continuous duty, or a odd shapes device marked BIM, will be the part your looking fior.

The emergency boost switch controls the same solenoid that controls chassis to house battery charging.

It will not be a latching solenoid, they are used for switching battery power on and off, Not interconnecting house and chassis battery banks.
