Need wiring diagram for cub cadet 1045

Brake switch
PTO switch
Seat switch
RCM / reverse switch

Could be any of the above.

Troubleshoot by checking continuity from the M (magneto) pole of the ignition switch to ground. It should be open (no continuity from M pole to ground.

Methodically disconnect switches until M pole to ground shows open. Then test suspected switch.

A DMM or an inexpensive auto circuit lamp tester will do.
