Tech got back to her - saying is short to frame battery error of some sort - shes waiting on New MK Gel - shes refused the ones they give out - which is what everyone should do if they use Lead
only reason i kept mines because its for indoor use only - or else i would have had MK Gel ordered instead -
18 is a neutral fault. Maybe joystick not in centre when turned on, or JS failure. 180 means theres a fault that allows 0 or 24v on to the frame. Usually a motor or wiring fault. 205 means power module fault...
