House battery to coach battery solenoid location.

[Ronald1955]

I needed to boost the chassis battery using the coach battery switch on our 2022 BT 5230 with E-350 Ford Chassis. I flipped the switch and the solenoid did not connect batteries. I am interested in the location of this solenoid and does the rocker switch get power from coach or house battery?

On our 5210 the switch is on the headliner behind the driver seat. You need to press and hold the switch down …. not just switch it once.

Thank you - we have the same switch location, I am looking for solenoid location connects both batteries.
