Still back to your earlier post, without the battery connected & no power the wheel should still turn and ride as normal in low gears. As I mentioned if the wheel does not turn then one suspects an electrical phase issue. So try the simple test I mentioned and disconnect the motor cable form the controller box to identify the fault better.
It will be from what I read a faulty controller or hub phase, I suspect a controller fault due to the arcing/melted battery connections and blown mosfets or melted phase wires at the controller end.
Hi everyone thank you all for your help.
Finally got to work on it Sunday and got some maitance in as well.
WP you were right the pawls had rusted up after an intense and consistent spary around the bearings it worked free. It began to no longer spin in both directions and works fine for normal biking now.
Just waiting on the new battery to be delivered and it will be back in action.
