We have recently aquired a 2005 Holiday Rambler MH with a 300 ISB Cummins engine. According to the temperature guage, normal running temperature seems to be close to 200 Degrees F.
When climbing a grade in warm temperatures, the temp starts to rise above 200. A weak buzzer starts, sounding more like crickets, with no warning light. As the temp rises the intermittent buzzer becomes more pronounced and regular. Upon descending the grade the buzzer gradually goes away.
Has anyone else experienced this and found the cause?
Thanks,
Jerry Howard
PS I also have a warning in heavy rain as covered in "WARNING CHIME" However mine is a high pitched beeping sound as opposed to a chime.
