    Got some disconnected wires and no 2 speed, indicator lights up but no action at the drive. Looked over several wire diagrams of different years and varying quality to read the numbers. Got three sets of wire, same numbers, but some are in white and some black? Any idea what that means?

    I recently bought a used '13 420F and among other issues I've found, the hand throttle dial doesn't work. I tested a few 420's at ritchie bros the month before I drove it and those didn't work either - is there some kind of safety switch or procedure to allow it to engage? It looks like the...

    D6k Ac compressor has no power.

    Does anyone have a schematic on this? Someone chopped up the harness behind the compressor presumably to bypass something but I have no clue what they did or which of these 4 plugs go to the low pressure switch, refrigerant switch or the compressor.
