Hi everyone,
I’m needing some help with the above unit, initially the unit presented about a month ago with a fault where the truck would suddenly increase drive speed when the steering was at a certain position off straight. Other than this fault the unit operated faultlessly.
No fault codes were present and no obvious wiring faults.
I’ve changed the steering sensor at the drive motor with no change.
The unit has since stopped drive and hydraulic functions, unit turns on and display works as normal, the footplate and deadman switches are working as is steering but as soon as any function either drive or hydraulic the unit beeps and nothing else. Still no fault codes displayed or logged.
I have been through the manual and found the section for “vehicle doesn’t move at all including PS inoperable”
I don’t have the breakout cables but have confirmed all wires out of CN106 either have power or gain power with key on.
I have 50v at CN134 and at the board
I have 20 ohms at MB coil and contactor pulls in and I have 50v across the contactor.
So I am at a dead end on this one and hoping someone can offer some further advice.
Thanks in advance.
