Must admit I thought of that too, but the active 2476-3 and 2474-3 voltage above normal codes will jam on the park brake.Just to throw in, in case I’ve missed it, but have you checked the park brake/hydraulic lock switch is okay?
We've also found why the codes are active...
If the LH joystick is not getting power on the 126 pink wire then neither are the 4 PWM signal wires that return to the ECM. The ECM detects this and sends a voltage down those signal wires "above the normal working voltage" of that PWM signal.
Eager to know the answers to Nige's last question above.Do you have 12v measured between the outlet side of the fuse (red arrow) and machine frame ground.?
While you are in there it might pay you to make sure there is power at the input side of the fuse (blue arrow).
Both of the tests above are done with the key ON.
