Code E-107, or No Power first thing to check. The wiring harness always breaks wires about 6 inches from the horn. If a horn wire breaks you will lose total power to the truck, have had a handful of these before, same area where the wires break each time.

hi, kurt, maybe a little delayed. Thanks for your assistance.
i still have the walkie pallet at shop, took the controller off the machine(1243c-4278),pluged the handset at bench test, notice that fld.min & fld.max parametres were= 0.2 both. it din't seem to me like a normal and change to fld.min=8 & fld.max=20, once instaleed back to machine,pluged again handset and turned it on. i relized that fld.curr. param. returned to 0.2 is it normal? Regards¡

I am not sure but I think I had this a few times because of a bad wire harness. Drive the truck and see if you get the code when steering all the way left or right. If it does there is a service bulletin with a new and improved wire harness.
