This is a common problem often caused by the potentiometer(pot) in the centre of the Wigwag (Accelerator.) This part takes a lot of “abuse” and the pot causes an intermittent electrical connection resulting in a very jerky ride. Try spraying a contact cleaner spray in the pot but most often the potentiometer will need to be replaced by a technician. Regards Chris…

Hi. Sounds like there is a faulty connection somewhere between the charger and the batteries. Are the batteries connected correctly. The charger uses the voltage level in the batteries to regulate itself. If there is a faulty connection, then the charge will not operate. Use a multi-meter to check if the batteries are connected correctly. There should be 24 to 26 volts across both batteries.
This fault can also be caused by a faulty charger socket. Check for any signs of melting or heat damage. There might also be a disconnected wire in the plug on the charger itself.Good luck. Neil.

Plamont unfortunately that flash code usually means a controller error. The controller is the brains of your scooter. Take the seat off and remove the rear shroud that covers the batteries and motor/gearbox assembly. Check all the wiring connectors for damage or loose connections. After checking the connectors turn the scooter on and see if you still get 8 flashes.
