The two switches you see have nothing to do with your problem. The one on the left is the battery disconnect switch - it simply takes the coach battery off line and is controlled by an battery disconnect intellitec relay located in the engine compartment. The switch on the right is for emergency start.
The battery isolator solenoid your looking for probably looks like this - http://www.amazon.com/Tekonsha-7000-Terminal-Battery-Isolator/dp/B0002UHVYQ - mine is located high up on fire wall in engine compartment.
The battery isolator solenoid separates the coach and chassis batteries so you don't accidentally drain your chassis battery. When you turn the ignition key the solenoid is energized allowing the batteries to connect and the alternator to charge both batteries. They tend to stick on occasion - sometimes rapping with hammer is enough to jar loose - replacements are not expensive and available at any auto parts house.
The battery isolator is the same solenoid that is used for the emergency start feature. However since this feature is used when the chassis battery is dead the emergency start switch uses power from the coach battery to energize the solenoid.
