ON A 2004 MONACO KNIGNT MOTOR HOME THE OIL SENDING SENSOR WILL GROUND OUT WHEN IT IS EXPOSED TO MOISTURE. (IE RAIN OR ROAD SPRAY) THIS CAUSES A FALSE WARNING BUZZER TO ACTIVATE. RESPONSIBLE ACTION IS TO PULL TO THE SIDE OF THE ROAD AND ATTEMPT TO DETERMINE THE REASON FOR THE WARNING BUZZER. POSSIBLE HAZARD IS BEING PULLED TO THE SIDE OF THE ROAD ON INTERSTATE WHILE MAKING THE DETERMINATION OF THE CAUSE. ANOTHER POSSIBLE PROBLEM IS THE IGNORING OF THE WARNING BUZZER DUE TO IT FREQUENCY ASSUMING THAT IT IS A FALSE SIGNAL WHERE THERE IS A POTENTIAL OF ANY NUMBER OF OTHER CAUSES. THE SENSOR HAS BEEN REPLACED, WIRE CONNECTIONS SILICONE SPRAYED, AND LIQUID TAPE APPLIED. MONACO STATES THAT THIS IS SOMETHING THAT YOU MAY HAVE TO LIVE WITH. CONCERNED OVER SAFETY OF PERSONS BEING EXPOSED TO THE HAZARDS OF STOPPING ON THE HIGHWAY. *JB
