Things You'll Need
Instructions
Start with the scooter's battery pack, if the scooter will not run. Make sure the switch is on. Next, check the breaker or fuse on your scooter. If you have a fuse, remove it, and hold it up to a light to inspect it for damage. If there is a breaker, flip it to see if it will reset.
Recharge the battery for 8 hours, checking it periodically to be sure it is charging. Be careful not to leave the charger on for more than 12 hours, as this will overcharge and damage the battery pack, if the charger does not turn off.
Push the scooter to see if it will start, if the battery is charged fully. Put one foot on the ground and one foot on the scooter. Make sure the switch is on, and hold the throttle fully open. Push off with your foot and watch for the motor to engage.
Check the wiring and other electrical components, if the unit will not start with a push. Remove the deck to expose the wiring and inspect it closely for any damage. Unplug and reconnect every connector, wiping off the male ends with a clean, dry cloth, to ensure the connections are not filmed over, damaged or broken.
Take a close-up look at the motor and speed control, looking for any signs or smells of burned or melted components. Replace the motor, if it smells and looks burned, since a damaged motor can destroy the speed controller.
Use a multimeter to check all fuses and/or breakers. Sometimes a breaker resets mechanically and is still worn out, and some fuses are difficult to find and check. Confirming continuity with your multimeter will let you know whether or not they need replacing.
Check the switch. Even though it may turn off and on, it could still need replacing. Turn it on and off several times, feeling for any flimsiness in the click. It should snap in both directions. Use your multimeter to ensure it is functional.
