If your electric scooter charges but won't turn on, it may indicate an electrical problem. Follow the steps below to diagnose and fix the problem:

Step 1: Check the Controller-Display Link Cable
Visual Inspection:

Action: Check the connecting cable for signs of damage, such as cuts, pinches, or loose connections.
Resolution: Make sure the cable is properly inserted into the controller and display ports.
Cleaning the Connectors:

Action: Dirt or corrosion may prevent a good connection.
Resolution: Make sure the connectors are dry before reconnecting the cable.

Do not hesitate to test the conductivity of the cable using a multimeter.
Step 2: Test Battery Voltage with a Multimeter
Preparation :

Action: Turn off the scooter and disconnect the battery for safety reasons.
Tool: Set the multimeter to the voltage (V) measurement function.
Voltage measurement:

Action: Connect the multimeter probes to the positive and negative terminals of the battery.
Resolution: Compare the measured voltage with the battery manufacturer's nominal voltage. If the voltage is significantly lower, the battery may be defective or insufficiently charged.

Step 3: Final Check of Controller and Display

After following the steps to check the cable and battery, if the scooter still does not turn on, the problem is most likely with the controller or the display.

• Probability of Failure:

  • Faulty Controller (90%) : In most cases, the problem is with the controller, which may prevent startup due to an internal failure.
  • Faulty screen (10%) : Less common, but possible, a faulty screen can also cause a power-on problem.

• Recommendation: In order to ensure a complete and lasting repair, I recommend replacing both the controller and the display. This ensures that your scooter will be fully functional.
