Electric scooter troubleshooting：you should know everything
Electric scooters are fun and practical, and yes, they can be maddening at times! Why? Like any electronic device or product, they sometimes fail. This may be due to a fall, a riding accident, poor riding habits, improper maintenance, improper operation, wear and tear, or simply because the elf living in it is not doing well. When it does happen, it’s good to know that you don’t always have to take the dead electric scooter to the repair shop, and with some basic electric scooter troubleshooting, you can solve the problem yourself. This article will help you identify and solve some of the more common problems, allowing you to start again.
How to repair electric scooters?
There are many forms of problems with electric scooters. Some are small and easy to handle by yourself, while others are more serious and may need to visit the nearest repair shop because they have experienced technicians and professional tools. The following are some of the problems you may encounter when using an electric scooter:
My electric scooter cannot be started.
The electric scooter can’t start. Troubleshooting the electric scooter
Problem: When you press the start button, nothing happens (no light or sound).
Possible cause: The power switch may be loose or malfunction.
Solution: Yes, it is obvious, but make sure the power switch is in the “ON” position. Otherwise, make sure it clicks or clicks in the open and closed positions. If it is not or feels loose, the switch may be defective and needs to be replaced. Some electric scooters need to be moved to start. Stand on the deck and push while fully engaging the throttle…Once you release the throttle, it should move.
Malfunction key or power switch (tool required: multimeter). The key or power switch is clicked in place and the display is normal, but the electric scooter cannot be started. In this case, you need to use a multimeter to perform a “continuity test” on the switch itself.
Why is my electric scooter not working?
Question: After confirming that the battery charger is normal, the electric scooter still cannot run.
Possible cause: This could be a wiring problem (loose or damaged), or a loose solder/weld seam on the battery. This may be due to excessive speed or driving on very rough roads.
Solution: Check whether the wiring is damaged, loose or disconnected.
Remove the deck panel located at the bottom of the electric scooter.
Check if the wires from the battery to the controller are connected/good.
Press down on the connectors to make sure they click into place.
The solder/weld seam on the battery pack is damaged (tool required: soldering iron). The connection between the battery pack and the controller occurs at various welding points or welding points on the battery. Press each point to make sure it does not loosen due to excessive vibration during use. If any solder joints appear to be loose when pressed, you need to reapply solder to make it firmly in contact with the battery. Take extra care when handling heated soldering iron tips near the battery area.
Burnt or melted insulated wires and wire connectors. Use your sense of smell to track any burnt or melted wires on or near the controller. Although this is reliable to a certain extent, even if there are no traces of burnt wires, your speed controller may still be defective. The speed controller requires professional technicians and special tools to be tested correctly. However, you can determine the problem through the process of elimination (that is, checking the battery ports, welds, fuses, etc.).
Why does my electric scooter go so slowly?
Problem: When you try to increase the speed, the electric scooter does not accelerate at all.
Solution: Check whether the speed controller is overheated, because this directly affects its operating efficiency. Any burned or melted wiring may be a sign of damage to the controller.
Brake lever failure: (Tools required: 1m wire or jumper). Since the normal setting of the brake switch of most electric scooters is on (it turns off the motor when braking), you need to disconnect the wire of the speed controller to see if the electric scooters are running. If it is normal, the brake lever switch needs to be replaced.
Some models are designed with a CLOSED switch. In this case, you need to disconnect the brake lever wire connector from the speed controller and “bridging” the brake switch connector terminals together. If the electric scooter is running, the brake switch (closed type) is malfunctioning.
The throttle of the electric scooter does not work.
Problem: The speed display and/or light does not illuminate you when you turn the throttle.
Solution: Due to the complexity of the throttle, the best solution is to locate the problem through the process of elimination and ensure that the wires are not loose or damaged.
Visually inspect the wires from the throttle to the controller. To check the wires, remove the deck panel located at the bottom of the electric scooter. Check if the wires from the throttle to the controller are connected/good. Press down on the connectors to make sure they click into place.
The battery may be exhausted or uncharged. See-Electric scooter is not charging
The fuse may have been burned out (tool needed: multimeter). See below-electric fuse location.
Test the connectivity of the throttle/controller (tool required: multimeter). Verify that the controller provides enough power for the throttle, and the throttle also sends a signal back to the controller. Test the red (+5V wire) and black (ground) wires from the controller.
If the reading is lower than the 4.3V – 5V output voltage, it means it is defective (or it may be any other components connected to it, such as battery packs, power switches, fuses, fuse holders, wires or connectors). If the reading is within the range, you need to test the throttle by measuring the black (ground) and green (signal) wires. You should get a reading between 0.8V-4.3V. If you get a zero output signal, it means that the throttle or throttle cable or throttle connector is faulty.
Note: The color of the wiring may vary from brand to brand.
Electric scooter throttle not working
The electric scooter is overheating.
Problem: The motor is overheating, and the wires or wire joints are melted or burned.
Solution: Check the motor. The smell of burnt plastic may indicate that the motor coil is overheated.
Burnt or melted insulated wires and wire connectors. In some cases, the insulating layer will melt the copper windings, causing short circuits and heating problems. Overheating of the motor coil will require replacement of the motor to avoid damage to the speed controller.
How to reset my electric scooter?
Problem: Your electric scooter is turned off or powered off intermittently during use, and sometimes the power switch does not light up.
Solution: In most cases, resetting the electric scooter can solve the problem.
Reset the scooter. Switch the electric motorcycle OFF and wait about 5 minutes. Then open the bottom deck panel and look for the reset button next to the battery. Hold for a few seconds. Now the power switch should be on, and the electric scooter should be able to work normally.
Electric scooter fuse location
Question: What should you do if the fuse or circuit breaker blows?
Solution: You need to remove the deck to access the fuse/circuit breaker. Check/replace the fuse and reset the circuit breaker manually if necessary.
Fuse or circuit breaker (Tools required: Allen wrench or screwdriver kit + optional multimeter for fuse testing). If you need to reset the mechanical circuit breaker, the fuse may be the culprit (if the fuse burns out, replace it with the exact type). In some cases, when the visual inspection does not reveal much information, you need to use a multimeter to test the continuity of the fuse or circuit breaker to determine whether it needs to be replaced.
Electric scooter does not charge
Problem: Your electric scooter is not charging at all or does not seem to be charging.
Possible cause: It may be that the battery is not fully charged or there is a problem with the charger itself.
Solution: The battery pack is not normally charged or not fully charged. This is usually the result of storing electric scooters for long periods of time. Try to charge the battery pack for at least 8 hours to see if it solves the problem. If not, you need to replace the battery.
Electric scooters cannot be charged
Battery pack voltage test (tool required: multimeter). The condition of the battery can be tested by measuring its voltage. Even if it is completely discharged, a good battery will give a voltage reading that is higher than its rated value. A lower rated voltage indicates that the battery pack has worn out.
The battery charger does not work/cannot charge the electric scooter (tool required: multimeter). The first thing you need to do is to make sure that the charger is not malfunctioning by plugging the charger into a power outlet… If the indicator does not light up or flash, you need to replace the charger. Otherwise, use a multimeter to test the charger when plugged into a power outlet. If the reading is zero or less than the battery’s rated voltage, the charger is defective.
Battery charger port test (tool required: multimeter). Unplug the charger from the power outlet. Next, while unplugging the power plug, plug the charger into the charging port of the electric scooter. If the indicator light on the battery charger is on when it is connected to the charging port of the electric scooter, it means that the wiring and the port are normal. The next step in reaching the voltage of the charging port is the same as the battery pack rating using a multimeter.
Why does my electric scooter always lose power?
Problem: Electric scooters keep cutting off randomly. Loose wiring can cause intermittent interruptions in power supply to the motor. This may be due to riding on rough terrain.
Solution: Every time you ride on a rough road, the electric scooter is powered off. If you see the power supply is randomly cut off, you can confirm that the line is loose.
The battery pack is not charging properly. Follow the steps listed above-the electric scooter is not charging.
Loose wiring. Follow the steps above-the throttle of the electric scooter does not work.
A wrong switch. Follow the steps above-my scooter cannot be started.
Motor failure (due to moisture penetration). The motor needs to be disassembled and dried.
How to adjust the brakes of electric scooters?
Problem: The brake response is not sensitive enough (you have to pull the lever hard to stop the electric scooter, or the brake is too sensitive).
Solution: Manually adjust the distance between the brake pads and the brake disc.
Adjust the tension of the cable to control the distance between the brake pad and the brake disc (tool required: wrench). First, to tighten the cable, loosen the brake cable stopper (this may require a wrench), and then pull the brake cable until it feels no longer loose. Don’t forget to tighten the cable stop again.
How to adjust the brakes of electric scooters?
Why does the belt on the wheel/motor of my electric scooter come off?
Problem: The belt comes off the rear wheel or motor.
Solution: The belt needs alignment and tension adjustment.
Adjust the alignment between the motor and the rear wheel and the belt tension (tools required: 2 wrenches). Aligning the belt requires the use of 2 wrenches (make sure they are the correct size with the bolt size of the adjustment shaft. First, loosen the bolts that fix the brake to the frame of the electric scooter. Second, loosen the rear axle bolts slightly. Now adjust the rear wheels, Make sure that there is enough tension and the belt is aligned between the wheel and the motor, and finally re-tighten the shaft bolt.
