any idea where the solenoid for the boost switch is located. The solenoid I found to be energized all the time is for the house batteries. If I **** the house batteries off the solenoid de energizes.So that makes sense. But there should be another for the boost switch no? Is there an isolator between the chassis batteries and house batteries so one does not draw the other down when nt running?

Thanks again, John
