    We'll need a complete machine serial number. Will also need a description other than won't move. Did it quit moving suddenly? Or did it slowly get worse, then quit? First lose a single gear or all gears at once? Fuses all good? The most common problem with those machines was the FNR.

    Any codes in the monitor? Do you know how to access codes? Check your F4 5 amp controller fuse. If that is OK, then make sure voltage is getting to the FNR, and through the FNR, and then to the TCU. There will be a 4 pin connector at the FNR with wire colors Red (Bat+), Yellow (Forward), Pink (Reverse), and Grey (Neutral). Check your messages.
