1. Unplug your charger from the port, then
click the power button to turn on your
scooter.
2. Use the multimeter to measure the voltage
of the battery, if the voltage is from 30-42V, it
means there is no problem with the battery. If
the voltage is lower than 30V, the scooter
maybe not be turned on.
If your scooter won't charge, follow these
steps and try again after each:
1. Check your charging cable and charging
port for signs of damage, like breakage. Don't
use damaged accessories.
2. Use the 220V ACA of the multimeter to
measure the voltage of the charger and
charger port, if there isn't reading, your
scooter probably needs to replace the charger
or charger port. if there is a reading, it
probably needs to replace the battery.
