The transfer switch is located in the same place on the Designer and the Pinncale.
It is behind the storage area panel that is next to the steps that go up to the bathroom / bedroom area.
If you remove the right side rear storage bay panel, you will see the transfer switch box mounted on a board.
Our Pinnacle has the new supplier / design transfer switch that is not on the recall. I removed the panel and checked it to be sure.
The transfer switch is only on units that are factory Generator Preped.
The transfer switch is basicly two large contactors that when there is a loss of utility power, the transfer switch transfers the coach power from the utility service power cord to the Generator power.
Below is a picture of my Pinnacle's transfer switch, notice to the left of the 1st picture is the backside of the steps going up to the bathroom / bedroom area.
The transfer switch's job is so the coach can only recieve power from one power source and the generator power can never be connected to the utility power source.
The block you see in the second picture between the two contactors is a interlock that allows only one contactor to be active at any given time.
Notice on the second picture the wires on top that connect the two contactors together, this is the coach power.
One set of the wires on the bottom go to the generator and the other side wires go to the shore power plug for the utility power cable.
