    just replaced the seat switch as well and still nothing? fuses are all good. making a hummimg sound when i turn the key on from one of the relays, but sounds like a fuel pump. im new to the equipment, but still plugging away trying to learn thanks

    There's also a sensor in the seat that is part of that circuit. The machine will stop if there's no weight in the seat. You might take a look at that.

    I have a door on mine. The door must be plugged in, or, if I wanna run doorless, the jumper plug must be installed.

    Does the hydraulic fan turn ? We have had more than one break the plastic flex plate that drives the pumps Pj

    yea if the park light goes off and still no go, you probabbly have a plastic disk failure. i had one on my 236

    Another issue could be the actual parking brake solenoid failed, I've seen that cause similar issue on several b series ssl, or the plastic flex coupler, but hooking up test gauges will tell the tale.
