Clark TMX12:
Code -066 is showing

The serial number is TMX250-2486-9597 KF.
The forklift will move about 2 feet before shutting down. It will restart each time. Anyone know what code -066 means?

Usually that code is a faulty controller
If it is 066 then master if a 66 slave but I have seen bad drive fuse give same symptom and code check 500 amp fuse first replace it
If still showing code it is faulty master controller

I would bet that the battery is going bad check the cells under load the problem with ac drive trucks the controllers are not forgiving if there is one weak cell the truck will not work not like dc trucks if the battery is weak it will still drive.

Code 66 is low battery. Check your leakage from positive to body(counterweight)
If its above 5.0 volts. It requires cleaning. Remove battery from unit and isolate.
They creep so you can charge it. Hydraulic cutout is a symptom of low battery.
