Good morning all. I'm new to this site. Hoping for some help with my Yale trucks.
I have some Yale model ERP9060VLE80TE08 80 volt battery powered trucks.
There is a problem that seems very strange. When you turn on key and press gas pedal the lift pump starts running and does not stop until you turn off. Of course this overheats the pump drive and starts overheating the hyd. fluid. You can even feel the heat in the steering column where the line run for the steering.
These trucks are difficult to troubleshoot and the mechanics my dealer sends over don't even know how to troubleshoot them. I would appreciate any help pointing me in the right direction on this.
Thanks
Rick
