almost sounds like a faulty seat switch
have you checked that?
you can temporarily bypass the seatswitch at the harness under the seat/hood and see if that does it.
If the truck has seatbelt light on dash then there will probably be 3 wires in that harness. You will have to find the 2 that control the seatswitch circuit and jump those and see if the truck comes on. The power steering should activate when the seat switch and direction control are both activated.
Not coming up with any codes. When the truck is acting up, you turn the key on and you can hear contactors pulling in, however the power steering motor will not be running. When you move the directional switch and hit the pedal nothing happens. A guy can be sitting on the unit with the key on wondering what too look at next and then all of a sudden the power steering motor will kick on and it will work. It is difficult to recreate the problem but it seems like coming off the battery charger has a higher chance of recreating it than anything else.
Thanks for you help.
normally if there are any problems with the truck it will show some kind of code on the display or a light will light up indicating which system is malfunctioning and that is normally accompanied by a code on the display.
A more detailed description of what the truck is or isnt doing would be alot more helpful.
-what happens when you turn on the key
-can you hear any contactors pulling in when you select a direction and mash the accelerator pedal?
just saying the hydraulics work but no drive doesnt really give us much to go on.
Any error codes showing on the dash???
