we have a 4840 and shortly after is runnung an alarm startsbeeping. It is coming from the left front pillar. It seems that if I slow it up or run it faster the alarm will try to go off. All guages including temperature are normal. When the alarm is going off the temperature light on the right side just barely will fiantly light up and go off. The motor usually hasn't been running 1 minute when all thsi starts up. Anyone have any ideas? Thanks Gene
