Seat Switch (OPSS)

For some reason the mast controls are operational when no one is in the seat. The seat switch seems to be working, since it alarms when parking brake is off and you stand up. Any ideas what's going on?

The truck does stop driving, and the seat alarm sounds... just has no effect on the mast controls. They work all the time.

Now that I think it through a little more, that bolt would have no effect on the other aux functions. So if they also operate without the seat switch activated, disregard the bolt.

If it lowers with the key off, you may have a lift lock bolt on the control valve backed off. I've used this feature to lower forks on a disabled truck, but I've never tried to lift this way.
