Photo A shown with the Door off. You don't want to run the generator for very long with the compartment door removed. It causes improper air flow which effects cooling.
Photo B is where you check the Oil. This unit uses approx. an 1/8 of an ounce of Oil per hour as part of the cooling process. Check Oil regularly.
Photo C is the connection for the Remote Switch located in the Living Quarters if so equipped. This connection services the Start/Stop functions as well as the Hour Meter.
Photo D is the Spark Plug.
Photo E is the Power Board or Control Board. This is the Computer / Brains of the Generator. If this part fails, the Generator will not run.
