5.9 Cummins engine, Temp buzzer going off, bus not running hot. Crank it cold, still goes off. Changed both temp units. Fan will not come on until you cross out front fan unit. Has anyone had this problem, or have wire scat for this bus? thank you.

The buzzer should come off the water temp light sender. Check to see if the wire is shorted to ground anywhere. A grounded sender wire will cause the light/buzzer to come on or the gauge to peg out at max temp, depending on what the wire goes to, and a gauge sender wire typically won't run a light/buzzer.

That is the problem we have, the head has 4 sending units, we know the back right is buzzer, but the others are unclear. We have nothing to go by as the wiring is concerned.
