I have a shark 48v, 13.5 AH battery pack that is not responding to the charger. I've done the easy BMS jump start procedure and no change. Luna Cycle recommended I do the more complicated version so I've opened the case but am not sure which of the cable connectors that plug into the PCB I need to disconnect and reconnect (there are 3, all white)
Do I do them all? is there a preferred order of disconnection/reconnection? I can send pictures if this helps
