Tips and Guide How To Fix An Electric Scooter

There might be several reasons for your scooter not to work. Let’s go over some of the main reasons that might be messing it up.

The most common issue that prevents your scooter from starting is the motor. You need to check the motor and see if it’s working properly. If the motor does not run, then your scooter will certainly not run.

You’ll need to check the throttle and use a voltmeter to see if that’s the problem causing the issue with your electric scooter. First of all, make sure that you charge up your scooter’s battery. And also, be sure to check if the fuse is ok or not.

You might need to inspect the motor and speed controller thoroughly. Take your time with it. If the motor is damaged, it’s obvious that your scooter won’t work.

But if the motor is working just fine, and your scooter doesn’t move, it might be a completely different set of problems. In that case, you have to inspect the power transmission system and see if everything is fine or not.

If the chain and the belt aren’t correctly installed, that might also cause this issue.

Malfunction in the speed controller can also interrupt the proper function of your electric scooter. Also, the belt can fall off from the rear wheel or the motor. That might be another reason why your scooter is not running.

You might be able to see how important a battery can be for your electric scooter. So, if the battery is dead, you won’t be able to start the scooter at all. You might need to replace the batteries after using it for an extended period.

Also, if the fuse or the circuit is blown out, that will not let you start your scooter. So, you should check for that and see if that’s the case with your electric scooter.

1. How to reset the controller on an electric scooter?

It’s not that complicated to reset an electric scooter. You just need to press down the reset button to reset the circuit completely. But it’s best to avoid overloading the electric scooter in the first place.

You should have a clear idea of why your electric scooter gets overloaded and requires a reset.

how to reset electric scooter

There is a certain capacity in which your electric scooter can function properly. But if you carry too much weight, that can cause issues. Also, the main problem creates from unsuitable riding conditions.

For that, you should always ride on solid and dry roads. That should help to give the scooter a bit more advantage in its capability to hold pressure.

Another thing that can create issues is the improper adjustments of the brakes. You have to consider looking at the user manual for guidance on how to adjust the brakes properly.

Remember, you should be careful not to overload the scooter. It will ensure that your scooter is at its optimal state and has more longevity.

2. How do I know if my electric scooter is charging?

It’s pretty easy as almost all the electric scooters come with a light. The indicator light tells you if your scooter is actually charging or not.

When you connect the charger properly, you’ll see the indicator light glowing. Typically, the color would be red, and it might be flashing. As it gets fully charged, the indicator light will turn green.

How do I know if my electric scooter is charging?

It will take at least 3 hours to fully charge up the scooter. But it’s not gonna take more than 12 hours at max. The time entirely depends on what type of scooter you have and all the other parts, such as the battery.

Most of the scooters use Li-Ion batteries. So, it’s not a good idea to charge it for too long. That will cause damage to your battery. You should take a look at the user’s manual and see how long you have to charge your electric scooter.

You can use a voltmeter. It’s a versatile tool that you can use to check for any kind of charging issue. That will help to show if the battery is charging properly or not. But as scooters take a couple of hours to charge, you should wait before messing with it.

3. How do you fix a scooter battery that won't charge?

The first thing you need to do is to inspect the electric scooter properly. Check for any loose wiring or anything of that kind.

If that’s not the issue, then the battery might be the issue. First, you have to check how long the battery has not been charged. A long period such as six months or so might damage the battery and make it defective.

Electric scooter worth the cost

If you think that’s the issue, then you should charge it for at least 8 hours. If the battery is not taking charge, then it’s defective. That might be the reason for the electric scooter not working.

You can certainly do a double-check. Just plug the battery to another e-soccer. If it runs, then you know, some other parts are broken inside. But that scooter doesn’t run, you know it’s the battery that is defected.

You might have to replace the battery and get a new one at this point. Make sure that you check before you buy it from the market. It should support your scooter model in the first place. Also, go for a better quality battery. It will help to give you more runtime on your electric scooter.

4. How to test the controller on your electric scooter?

This might be a tricky test to run. You can’t just test the controller separately, like every other    

The electric controller runs the whole e-scooter. From getting the power from the batteries to running it through the motors, it’s one of the most important parts of an electric scooter.

It helps to control the speed of your ride. It’s super essential for anyone who hits the road with any vehicle, whether big or small.

electric scooter repair guide

If the electric scooter controller malfunctions, the scooter will not run. To identify the problem, you’ll need to check every part of the scooter that’s connected with the controller. Then see if they are working correctly.

If the parts that are attached to the controllers are working fine, then the controller doesn’t have a problem. But if any of the components fail, it might be either that particular part of the controller.

Either way, you’ll need to fix this to make the e-scooter functional again. That might require a replacement. Or a simple repair might be able to fix the issue as well.

5. How do you fix a pulse on a electric scooter?

The process of fixing a pulse on an electric scooter is very simple.

All you’ve got to do is move it manually for a bit. Sometimes if all the parts and mechanisms are ok, the scooter might just need a little bit of push to go. For that, move the scooter with your hands on the throttle.

When you are moving the e-scooter, turn the throttle. It will start the motor. If it doesn’t start right away, give it more space. You might need to run it longer to be able to get it running.

But again, if the whole interior mechanism is not ok, then this technique will certainly not work. As the pulse issues mostly are seen on scooters that haven’t been used in a while. So, you need to make sure that all the other parts are working properly.

For that, check every single part individually. You might need to fix or replace some defective pieces.

First of all, the battery should be functional, along with all the other vital parts. Motors, circuits, etc. are the critical parts you should check. If those are working correctly, you can use the shown method. Hopefully, it will get the scooter running for you.

6. Why isn't my e-scooter going fast?

A lot of things come into play when you ask why your scooter is going slow.

The main reason for that kind of lack of speed is a weak and old battery pack. A worn-out battery will never be able to provide enough power in the motors to get the speed that you crave.

The shortage of battery charges also causes electric scooters to run super slow. It’s optimal to keep your battery at more than 10%. Anything less than that might slow down your ride drastically.

Another thing that can make your electric scooter go slow is the motor. It might not give the output necessary for getting the speed in your electric scooter, But for most cases, the motor is typically not the issue causing the lack of speed.

The throttle can also be a part that slows down the electric scooter. But it’s an extremely rare scenario. The magnet inside the throttle controls everything. If it comes off, that might lead your ride to be super slow.

But in these cases, the throttle will seize to work completely rather than slowing down your ride.

Finally, the speed controller of your e-scooter can create the issue of low speed. But again, it’s not likely to happen. Like the throttle, it will completely stop working. If the controller overloads, it will create identical problems like that. Thus, it is not able to transmit power into the motor.

7. Why won't my electric scooter hold a charge?

Any type of charging issue is mainly caused by a faulty battery or a charger.

As batteries get older, they lose the charge holding capacity. Also, they wore out and got weak. It’s recommended to replace a battery after an extended period of usage. That keeps things fresh and working at its best.

A defected charger can also affect how long your scooter can hold the charge. You just simply need to pick the right voltage supported charger for the batteries.

If you charge your batteries with less voltage, it won’t be as nearly effective. And if you charge it with too much voltage power, that will create problems. Both of those will damage the battery for the long term. And of course, your electric scooter won’t be able to hold a charge.

That doesn’t guarantee that moderately new batteries won’t lack the ability to hold a charge. Sometimes there is a leak in the battery that can cause this issue. It’ll be better to replace the battery at that moment. If you have a warranty, that would be great.

Electric scooter troubleshooting

Now that you know the reasons behind your electric scooter not running, the troubleshooting part would be much easier. In most cases, you’ll be able to fix the smaller issues all by yourself. That saves you money that you don’t have to waste on repairing it.

You certainly would not be able to fix everything by yourself. You would probably need to take it to a professional. But it’s good to know the basic troubleshooting for your scooter.

electric scooter troubleshooting

As you can tell, it’s not the best idea to mess with the e-scooter if you don’t know what you’re doing. Let’s go over some of the basic techniques that you can use for troubleshooting.

But first of all, you’ll need to identify which part is causing the issue. That would make it easier to fix afterward.

1. Inspect The Motor Thoroughly

The motor runs the whole electric scooter. And typically, this is where you’ll find most of the issues. It’s powered by the battery of the scooter. And the speed controller directs the power into the motor.

The most common problem with the motor is overheating. That can cause some of the wires to melt or burn. Those melted wires can cause a short-circuit and damage the motor

Why is my electric scooter not working

These short-circuit can permanently defect the whole motor. But in most cases, changing the wiring would work. So, first, you have to look out for any wires that are burned or melted inside the motor.

That indicates that your motor is taking too much pressure from the speed controller. Thus, any short circuit in the motor can burn out the speed controller as well.

So, be sure to look precisely at every wire inside the motor. Look at the circuits and see if there is anything messy. Those are pretty complicated stuff to fix by yourself. Consider taking it to a professional as they will repair it without damaging the motor further.

But if it’s already damaged to the point of extreme, you might need to replace the motor of your electric scooter.

2. Check the Battery and Charger

To check the battery, you’ll need a multimeter. The multimeter will show you the condition of the battery pack of your electric scooter.

Attach the multimeter to the battery. You should get an even indication. If it bounces back and forth, you know the battery has defected somehow.

Also, the voltage level indicated in the multimeter should be above its rated voltage level. That is the condition in a good battery.

How do I know if my electric scooter is charging

. Even if it was fully discharged, or it was in storage. A good e-scooter battery jumps up above the rated voltage level after the scooter is driven. It’s not going to take more than a few minutes for you.

Now to check the charger, you won’t need any special tools. You just have to plug it into the socket. Take a look at the illumination indicator light. That should stay stable for the entire time.

If you see that it’s blinking on and off or the light doesn’t lit up at all, you know that the charger is defective there.

But despite the illumination, it can still cause issues if it’s not properly sending output to the battery. To check that, you can use a multimeter. You see, multimeters are a very useful tool when it comes to running any kind of check on your e-scooter.

So, use your multimeter and check the output voltage. It should be a little bit above the battery charger rated voltage. But if it’s not, that can cause your battery not to charge properly. It is even damaging the battery over time.

3. Check the Fuse or Circuit Breaker

Overloading or excessive heating can cause fuses or circuits to burn out often. Some short circuits can also burn the fuse of the circuit breaker.

You can’t track down every burnt out fuse or circuit breaker. If you want to check those, multimeters are your best friends. That will be the most efficient way to a thorough check.

Electric Scooter Throttle Not Working

A properly functioning electric scooter’s light and the speed display turns on when you twist the throttle. But if that’s not the case, you might have an issue with the throttle. Just remember that it also can be caused by the loss of connection between the controller and the accelerator.

A malfunctioning throttle can stop your e-scooter from starting completely. Or it can create issues while you are riding it.

4. How to Test the Throttle

To check, you need to turn the scooter off first. After that, simply remove the switch from it. You should give it the most priority because it ensures maximum security in the first hand.

electric scooter throttle not working

After that, you need to lift the back wheels. Connect a 4.3 voltage DC positive wire to the red wire of the throttle. Then you need to connect the wire that is black to the ground. There would be a green or a blue wire that you need to fix along with the black wire with a voltmeter.

Then you can put the fuse back and start the engine. Twist the throttle, and you should see that the motor should be turning and functioning properly. If not, then the battery might be the issue that’s causing all the throttle not to work.

After identifying the issue, it’s going to be much easier to fix it. Just make sure you take your time with the voltmeter. 

5. Test Power Switch or Key Switch in a Proper Way

It’s fairly simple to run a basic test of the power switch or the key switch. Just use the switch and turn it on and off several times. You should see a pop motion each time you do it. It should snap. If you feel that the switch is loose, it might be defective.

It’s worth it to check the switch with a multimeter, whether the switch snaps or not.

6. If the motor is still not working, just go through the following steps.

First of all, turn on the power switch if it was off. If not working, you might have to look at the fuse and the circuit breaker and see if anything is damaged. You also should check the lever switch after that.

Now, you have to check the battery and test if anything is defective. The port is another important thing to look at if that has any kind of defects. After a thorough check, charge the scooter for a couple of hours.

Giving the scooter a push can also work sometimes and get the motor running.

7. What if the Motor Runs but Scooter Does Not Move

This problem has nothing to do with the motor of your scooter. That’s usually caused by power transmission system issues. Check it and see if the chain is in place. If not, get it back in place.

If the chain falls consistently, you might want to consider investing in a new chain. That will solve the issue for good.

8. What if the Speed Controller Does Not Work

Just check all the parts individually that are connected to the controller. The voltage of the battery also might affect it. Check it and give the scooter a push while turning the throttle. Surprisingly enough, that works sometimes.

9. What can I do if the belt fell off of the rear wheel or the motor?

You can simply put it back in place. Or if it’s damaged, you’d have to change it. Just make sure to select the right sized belt.

To do that, first, measure out the whole length and width. That will help you get the replacement properly.

10. What if the Key is Lost

For that, you must get a key replacement.

11. What to do if Batteries Loose Power too Quickly

If the battery is old enough, you might have to replace it completely.

The charger, the port, and the voltage of electricity provided can also affect the battery life of your scooter. If you find any leakage, that might be another reason for the quick draining of power.

12. What to do If the Fuse or Circuit Keeps Blowing Out

As the main cause of the fuse to blow out is overloading, you should be considerate of it. Check if the power transmission voltage is at an optimal level or not. It’s very important to have a stable and even volt power running through the controller and motor.

13. What to do If the Brakes Do Not Function Properly

First of all, you need to inspect the brake pads properly. Read the user’s manual and see what’s the best cable tension for your e-scooter.

Then simply adjust the tension of your brake cable. That will fix it for you. Also, make sure that you maintain what you adjust. Brake shoes tend to lose adjustment some times. You should be mindful of that and adjust it from time to time for optimal performance.

14. What If the Motor Runs Constantly

Typically, the speed controller will create the issue.

You need to check the throttle and speed controller for any problems. You might need to replace the speed controller to solve this problem.

15. What to do if the Battery Does Not Take Charge

If the battery is in good condition, the charger or the port might be the issue. Try switching the charger and the port. You should charge the battery for at least 8-10 hours.

If the battery still doesn’t take charge, you should use a multimeter to check the voltage. That will tell you if the battery is good to use or not.

17. What to do if the Motor Runs Slowly

As you can tell, the main reason for the motor running slow is a weak battery. As it fails to deliver the power that’s needed, the motor speed decreases drastically.

It also can be for the misadjustment of the brake shoes. You should adjust the brake cable tensions by following the owner’s manual. That should solve the issue unless the motor is defective.

Final Words

Now you know all the basic electric scooter troubleshooting that you need. As you saw, some of the problems have pretty quick and easy solutions.

But you should never mess with any of its parts if you don’t know what you’re doing with it. That will prevent you from damaging the e-scooter in the process of fixing it.

Going for professional repairs and fixes are the best way to go. They will fix all the problems you have within a short period.

But it’s always better to have an idea on it as you saw on the tips & guide on how to fix a electric scooter. Hopefully, you’ll be able to use them next time your shooter requires the basic troubleshooting.
