Have Tilt, No Lift

[eltonb]

Have a Gehl 4835, everything was working fine, but while using the machine, it stopped lifting UP or DOWN - you can hear it try, but it wont - it behaves the same way as it would if the safety bar were up. (1) When I have the safety bar up, the bucket will tilt, but it wont lift up/down. This means the switch is faulty or has been bypassed, but if it tilts, it should lift up/down. Right? (2) When I sit up out of the seat, the bucket will not tilt - this means seat switch is working. (3) When I have parking brake on, it will not tilt or lift. This means parking switch is working. Is there just 1 solenoid for lift and tilt? If so, since it tilts, this means the solenoid is good right? Is there a relay for lift and tilt? If so, where are they? How to test? What would cause it to tilt but not lift? Thanks! -Brian
