Hi all,
I have a reach truck with no drive. if you press the accelerator pedal down fully after about 3 seconds the truck shoots forward at full power( I think the bypass contactor is coming in ) they is no pulse to the drive motor. Has anyone had this fault before, could it be the accelerator pedal if so how do i test it?

HI there

If this uses the old Mikropulse system, you can look at the drive controller and on the logic card LCD display segment there should be an indicator with an error.
