05' Pete 379 with a Cat ACERT: The last few day's the engine fan has been staying on 90 % of the time. The air solenoid on the firewall has no power and the manual rocker swich has power only on one side "the yellow/orange wire".
The Horton clutch seems to be in good working order and will release with air pressure.
Occasionally the fan does cycle correctly but not often.
Opinions or suggestions appreciated.
