just realized my pto light does go on... when switchedJohn,
We posted the wiring earlier in this thread but here is a simplified excerpt more specific to a front PTO only configuration on a
Note that the lamp and the PTO winding are wired in parallel and switched at the same time. If the dash lamp is not burned out, and it still does not come on when the PTO switch is turned on, then there is no voltage at the #790 blue wire from the TDCM terminal X13 pin 4 to the PTO switch. Possible reasons for this could be a bad F2 10 amp fuse or its holder, or a failed seat switch or an open in its wiring harness leading up to X14 pin 9. If there is no voltage on pin 9 then the time delay module inside the TDCM will switch the relay contacts D off and disable the PTO. Use your volt meter to verify the voltages at these points. Test these things and let us know...
