Understanding the Possible Causes of the GXL v2 Throttle Issue

There are several factors that can cause the throttle not to work correctly:

  • The battery might not be providing enough power.

  • The brakes could be interfering with acceleration.

  • The throttle itself may not be functioning.

  • The throttle wires might be old or damaged.

  • The controller may not be working properly.

  • The motor might not be responding.

Troubleshooting and Resolving the Gotrax GXL v2 Throttle Issue

Following are the steps to resolve and fix the Gotrax GXL v2 throttle issues.

Step 1: Checking the Battery 

Start by checking the battery. This is easy to do. If the scooter’s LED lights and other accessories are working correctly, then the battery is likely fine.

Step 2: Resetting the Scooter

A fresh reset often eliminates many issues and might also eliminate this one. So, first of all, try resetting the GXL v2.

Step 3: Inspecting the Brakes 

Ensure that the brakes are not engaged when you turn on the scooter. Make sure the brake lever is in its normal position and not stuck, and check that the brake pads aren’t touching the tire even after you’ve released the brakes.

Step 4: Examining the Throttle Handle

Take a close look at the throttle handle for any visible damage or loose connections. Make sure it’s securely attached to the handlebars. If you spot any problems, tighten or replace the throttle handle as needed.

Step 5: Verifying and Fixing Throttle Functionality

To determine if the issue lies with the throttle, follow these tests: 

1. Testing Throttle Wiring:

  • Disconnect the throttle wires from the controller.

  • Use a voltmeter set to DC voltage to test the throttle wires. Twist the throttle and check if the voltage reading changes as you accelerate and decelerate.

  • If the voltage changes consistently, the throttle is likely working correctly. If not, the throttle may be faulty and should be replaced.

2. Directly Applying DC Current:

  • Disconnect the throttle wires from the controller.

  • Manually apply a low-level DC current to the throttle wires using a power source like a 12V battery. Connect the positive and negative leads to the corresponding throttle wires.

  • Observe whether the motor engages when you apply the DC current. If the motor responds, it indicates that the throttle is causing the problem and needs replacement.

Fixes for a Faulty Throttle

If the throttle is found to be faulty after the tests, you’ll need to replace either the wires or the entire throttle set. The issue could be with the connections or the throttle’s functionality, and both may require replacement.

Step 6: Verifying and Fixing the Controller and Wiring

If the throttle passes the tests, the issue may lie with the controller or wiring. Here’s how to check: 

1. Checking Wiring Connections:

  • Inspect all wiring connections between the throttle, controller, and motor for loose or damaged wires. Ensure that all connections are secure and free from corrosion.

2. Testing the Controller:

  • Disconnect the throttle from the controller.

  • Use a voltmeter to check the voltage output from the controller when you operate the throttle. It should show a corresponding voltage change as you twist the throttle.

  • If there’s no voltage change, it could mean that the connections are loose or unstable, or the wires or the controller itself is faulty.

Fixes for a Faulty Controller and Wiring:

If the controller and wiring are found to be faulty, they will need to be replaced with new ones. Contact Gotrax customer support for replacement parts.

Step 7: Inspecting the Motor 

If none of the previous steps resolve the issue, it’s possible that the motor is not responding. Test its functionality by applying a DC source to its connecting wires and observe its behaviour. If necessary, replace or repair the motor.

    If resetting the scooter doesn’t work, you should inspect the brakes, throttle handle, and throttle wiring for potential issues.

  • What if the throttle is found to be faulty after testing?

    If the throttle is faulty, you may need to replace either the wires or the entire throttle set, depending on the specific issue.
