How To Fix An Electric Scooter Throttle That’s Not Working

Electric scooters are an excellent means of transport and mobility. And you don’t need to pay much before usage 

You only need to get it plugged fully charged with electricity before you set out for your destination. 

But at some point, problems occur with our scooters and they refuse to work. 

Most times, when the battery is well charged and they don’t start,  it’s usually as a result of the throttle not working.

To get your scooter to work, you need to test the throttle. 

Let’s look at what a throttle is.

What is a Throttle?

A throttle is a device that controls the flow of fuel or power to an engine.

There are various kinds of throttles in electric scooters.

There’s the half effect throttle which is the standard throttle. It is sometimes referred to as a hall effect throttle, accelerator or twist bar.

Other throttles include on and off throttles, high-end throttles, full twist, half twist, thumb foot.

How to Fix The Throttle of Your Electric Scooter.

Here’s the step by step process by which you can test your electric scooter throttle when it is not working.

Prepare to Test

To prepare your electric scooter for testing, move it to an isolated area. 

Ensure there’s an adequate electric supply to test your scooter in the area and make sure it is on stable and ground mode. 

As an alternative, ensure the batteries are also well charged. 

Test The Throttle

The throttle is easily identifiable in your scooter and normally comes with 3 colored wires (red, black and green or blue)

Twist the throttle to test if it is the one. If you notice the speed display and lights of your scooter don’t come on, the connection between the throttle and controller is probably faulty.

Turn off the electric scooter and remove the fuse. Lift the back wheels of the scooter off the ground. 

Then, connect a 4.3 Volts DC positive multimeter to the red wire of the throttle, the black wire should be connected to the 4.3 Volts DC ground. 

Next, take the Voltmeter and fix it to the black and the green or blue wire. 

Put the fuse in and put on the engine of the electric scooter. 

Twist the throttle to start the motor and if the motor turns and the scooter starts, then there is an issue with the throttle. 

Plus, if the number on the voltmeter is low, then there is an issue with the throttle. The voltmeter should ideally read between 0 to 3+ Volts.

Also, if the electric scooter doesn’t start when you twist the throttle, then the problem is either with the battery, ignition key or the connection to the controller.

Fix The Issue 

If the trouble is with the battery, then you may need to replace it.

If the issue with your scooter is with the connection between the controller and throttle, then you need to take it for repairs at the nearest electric scooter repair store to get the problem properly diagnosed and fixed.

In worst scenarios, you might need to replace the throttle entirely so be prepared for such outcome.

Better still, if your electric scooter still falls within your guarantee period, you can get in touch with the company that you bought it from and request that they replace the parts for FREE or at a reduced cost.

Final Words

When your throttle doesn’t work, it halts your activity with and renders your scooter inactive.

But with these tips shared above, I’m confident you can find a way to diagnose and repair your scooter when the throttle doesn’t work.

Test your electric scooter’s throttle to diagnose the problem and if it is a problem with your throttle, the multimeter will detect it and you should get the throttle fixed.

If you cannot do it yourself, make sure you seek help from an expert.
