Thanks for your help. I did find the contactor and checked. thier funtioning ok powering off and on both the bottom one and the top one but one thing that is strange is that i cant controll the lift from the service pannel which i was suppose to if i cant do it from the platform. I did tried to override the hand sensors and that doesnt work eather. thanks. any more suggestion will help.

The contactor itself will be located under the floor board close to the teavel alarm....towards the front

Will be on the ground control panel.... BIG red button you push to disconnect the power in an emergency,might also be one on the platform control station also.......

Thanks I know the code but can't find where the ed-contact is can you help cause it not move or lift even when controlling from the service panel. Thanks

Static return to off during operation....

Possible causes:

Attempted to move vehicle with out hands and feet in place
Open ED-B contact or related circuit wiring
