Hey all, got a sc4000 here and in forward and reverse it moves but not at full speed. I'm just a maintenance supervisor here at my company so I'm not forklift mechanic I just try to fix what I can.

No codes on the display, so far ive measured battery volts at the battery and have 36V and I'v disconnected the hight limiti switch which didn't effect the problem. What can I look for to fix this thing.

Thanks
Cole
