    I have a kenworth t680. The ecm fuse blows when the clutch fan engages. If I disconnect the solenoid it runs fine. What could it be?

    Chase the ECM power wire after the fuse. It could be rubbed thru on the fan solenoid wire.

    So I changed the solenoid now the fan stays running. But so does the truck
