Testing the Charging System

 

 

To test the charging system, a multimeter or voltage tester will be required. If the scooter is not 
recharging properly, testing the output voltage of the charger, and voltage at the charger port, will help 
narrow down the issue may be. 

1.

 

Testing the Charger 

To test the output voltage of the charger, plug the 
chargers power supply directly into a wall outlet, 
but not into the scooter. Set your multimeter to 
DC 200 or higher and insert a multimeter lead 
into each of the two parallel prongs as shown in 
the photo below. 

 

If the charger is working properly, it should be 
emitting anywhere from 54 volts to 57 volts.  

 

If the charger is not working properly, please 
contact EWheels service department directly for a 
replacement.
