My daughter has a Razor e100 for a couple of years now and it has been running perfect. On the weekend she was using it and whilst going up a hill it cut out. Completely dead, not even the on and off switch lighting up! I thought it might have been out of charge so tried to charge it but the green light on the charger stays green instead of going to red, although the on and off switch on the scooter does light up if switched to on whilst charging. I opened up the scooter this evening and tested the voltage across each battery and both showing about 11.4 volts. I also tested the voltage across the batteries whilst charging and the 11.4 volts does not increase at all. I have also tested the voltage coming from the charger itself which is showing 25.5. Any help would be much appreciated.
