Seems to die when fully charged. one push with foot and it lurches forward and runs a while then won't go again after stop until manual push and then lurches forward again. is something not connected securely>

Hi ,

so first take off the seat, please be carefull how you do this as they can be heavy,

Now remove the cover , again carefull as there may be some wires connected for the lights so discconect these,

Now look for the break located on the side of the motor ( can be a gold colour), check the wires here, make sure they are a good connection, now check the battery teminals , are they loose check the wiring here, now does the brake click when you move the throttle lever, it may be a really faint click, no click then check the connections leading to the controller, normally a black or blue box.

IT could also be the fact that the batteries are faulty and appear fully charged, again check the charger making sure it is really charging , last of all it could be in fact a controller fault or brake fault

Please rate my help.

Regards,

Check to make sure the free wheeling lever in the rear of the scooter is fully engaged. Try engaging and disengaging it a couple times.
