A Segway ninebot ES2 scooter came in today with power issues, customer pointed out that the scooter sometimes works fine until she switches on the main light. When switching on the main light the scooter motor looses power and struggles to go up any sort of ramp or hill and will not go past 14 Kph.
Fix
It is evident that this model and also the ES! and ES4 share the same problem, the control board for the motor over time deteriorate and when switching on the headlight the voltages change slightly across the board, this change in voltage and resistance causes the board to direct power away from the motor and also send mixed signals to the 3 phase motor. In this case we replaced the control board and the scooter now works absolutely fine.
