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.

Hello

Check the following:

* Circuit breaker on main control box is tripped
* Fuse blown (check fuse in main control box assembly).
* Incorrect polarity at battery terminals
* Dead batteries.
* Charging cable is still connected to charging receptacle
* One of the cable connections at the main control box is loose.
* Control connection cable disconnected
* Broken key switch
* Throttle stuck fully open
* Throttle control potentiometer broken.
* Speed potentiometer broken
* Battery voltage too low.
* Faulty charging cable.
* Charger not working.
* Charging circuitry in main control box assembly not working


If these check OK, the problem is likely to in the control connection cable or upper control box Verify that the upper control box is getting 24V. (Blue wire on red connector.)

* If the upper control box is not getting 24V, replace control connection cable

* If the upper control box is getting 24V, check key switch operation and verify wiring in the upper control box. Trace voltage from keyswitch on to find where the problem occurs. (Replace upper control box if necessary.)

* Charge batteries with a 12V charger or replace if necessary.

* Ohm test the charging cable - replace if necessary.

* Test scooter with a different charger, if new charger works, replace charger.

* Check wiring in main control box assembly - replace in line relay if necessary
* If batteries, charger, and all wiring is good, replace controller PCB. (Note the model number for the PCB, for example 1208-2330.)

Just bought my dad a second hand go go 3 wheel elite scooter


Hi Linda. Sometimes if there is a blown fuse or faulty connector on the battery leads, the charger thinks the batteries are charged as the voltage coming out of the charger rises to the high level. Some chargers will cut out if this happens. It is probably not the charger.
Make sure the batteries are plugged in correctly, sometimes during transport they will get knocked and become disconnected.
Also make sure that the battery terminals are not loose where the wires connect to the batteries.
Good luck. Neil.

I have had this charging overnight but it won't charge. What should I do?


Hello Friend,
It depends on what you mean by charging overnight.
1. When you connect the charger, it shows on the phone that it's charging but after a while if you unplug the charger, it's still not charged: if it's the case, that means the battery is dead and needs to be replaced.
2. When you connect the charger, it doesn't show the phone charging: in this case it can be the charger brocken or the phone charge connector is faulty. you can verify that by moving the charger connector a little bit and see if it will start charging, if not you can try with another charger. if it doesn't charge even with another charger, at this time i will say for sure that the phone charge connector is faulty and needs a repair.
Best Regards,

Battery charge indicator seems faulty.


Solved own problem. Bad conection between pcb and battery contact pins. Reheat each battery pin on the pcb carefully until solder reflow occurs then remove heat. PDA now repaired
