Here is another option for the solenoid.

On my coach that solenoid has 2 functions. One it is the boost relay and second it combines the coach and chassis batteries when the coach is running. They provide power to the solenoid and then ground it to activate it. When the engine is running the ground is through a oil pressure switch. The Boost switch just provide a ground circuit.
On my coach the battery charging circuit is separate from the boost/combine solenoid.
