Not sure of the exact model#, all I can make out is RR52 the rest is gone. The serial# 1A234764 if that helps. One day while lifting it beeped and showed an overheat message, lift motor was hot to the touch. Let cool down overnight, tried again the next day. Lifted a pallet about 4 feet and completely shut down and would not reset. Lowered the forks manually then powered unit off and back on. Went through self test, as soon as you push on foot pedals the wrench light comes on and access 3 blinks 367. I don't have any crown manuals so I'm going in blind. Any help would be greatly appreciated.
