Hello! Let's see if we can work together and come to a satisfactory conclusion!

Expert:  Curtis B. replied 10 months ago.

the seat switch and seat belt safety switches are what controls the hydraulic lock on the control valve. They close a relay, looks like a starter solenoid , and solenoid has to activate and keep the lock valves in the control valve open. Do you get indication the safety switches are working? If so, check the solenoid, it may not be closing.

this is a intermittent problem. I crossed the seat switch but haven't done anything to the belt switch. I haven't been using the belt at all. is the switch by the belt itself? and where is the relay located at? also I just bought this and was working great this seemed to happen after I pressure washed it.

Looks to only have seat switch and operator presence switch on operator bar. The relays and circuit breakers are under fuse cover, shown below. May be bad relay. See link below.

Do hear relay close? If not relay not getting power from safety switches. Is power getting to the lock solenoid?

Customer: replied 10 months ago.
What one is the relay for sure. The park light goes on and off. Where is the solinoid located at?
Expert:  Curtis B. replied 10 months ago.

#15 and # 17 are the solenoids that lock the control valve, and have to have power from relay. See link below.
