Just for kicks. Make sure ALL your interior Coach lights are OFF and retest the system. The Difference between IGN ON and the Engine ON, is, you will have 1 to 2 volts(13.2 to 14.4) HIGHER dc voltage to the coach system. That may affect the operation. Also, with the engine running, turn on the Dash AC system and the headlights and see if it malfunctions. Those 2 things will drop the Chassis voltage by at least 1 to 1.5 volts. That will help you figure out if it is a HIGH dc voltage problem. Also, get a digital dc volt reading of the chassis system when the engine is ON. Make sure your Alternator is not putting out excess voltage. Doug
