Make sure it is not battery or motor, jump the battery + & - to the motor + & -, if it works it will be the control box
30 minute fix for very cheap
ITEMS NEEDED
Get a Potter & Brumfield relay (5 poles)
2-3 feet of wire
4 female wire ends to plug into relay
HOW TO FIX
Take apart razor so you can see the black control box
Unhook throttle plug, this is the one with 4 wires (2 brown & 2 orange on mine)
Wire relay:
85: Ground
30: Red wire from switch to control box, if you wire this straight to battery it will work with switch on or off (killing battery)
87: Red wire to motor
86: Brown wire from throttle plug
Run a wire from 12v (battery) to other brown wire on throttle plug
END RESULT
When the throttle is activated, it closes the loop in the brown wires, triggers the relay, activates the motor
You WILL NOT have the throttle control, it is wide open or off when you activate/de-activate the throttle
This will save you $30 for a new control (brain) box.
Does the Razor charger light go straight to charged? If so the battery has gone & needs replacing, please check the voltage output & load test the battery (weight on scooter while battery connected straight to motor). very common but overlooked issue can just be the On/Off switch, check there is voltage present across the terminals. If you are hearing a clicking noise then the control module may have gone.
