Thanks,
How did you troubleshoot it? Where is sensor? In Batt compartment? How do I know which model of CMP I have? You state yours is a 20. The "Maintenance book that was apparently supplied to the original owner of this bus is dated 1991 and there have been many changes between its publication and 1995! Makes it an adventure to find and fix things.
I pulled the CMP down and it appears to have several stacked circuit boards in an aluminum housing, No sign of overheating etc. Would like to fix this.
