Everyone is discussing merge solenoid which I think should not be needed when driving down the highway. It is basically an emergency switch to connect the two battery banks to start the engine when the engine batteries are down. In my coach the isolator is located in the electrical compartment which opens from the back and is located just above the merge solenoid. It is much bigger than the the merge solenoid and all motorhomes that I have owned have one. It is the device that allocates charge to the house and engine batteries. I will take and post a photo.
