2012 forest river Solera emergency start switch

The fact that he has a solenoid doesn't necessarily mean he has an emergency start switch. My 31K Itasca has a solenoid next to the house battery, but I don't have an emergency start switch.
My solenoid I assume, is either for the house battery disconnect, or the charge solenoid which charges the house battery when the engine is running. There is no provision to use the house battery to aid the engine battery.
