Note:

Model versions can be determined based on the product ID code on your Razor product. The product ID code can be found on the battery cover and/or on the bottom of the frame. The 7th and 8th numbers in your product ID code are the version number of your Razor product (e.g. "01" = Version 1, "02" = Version 2, etc.)

Warm Tips:

• Most electric scooters and electric bikes have controllers which were made specifically for that model. Please carefully confirm the model number of controllers before buying.
• If a controller is available that will plug-and-play directly into an electric scooter or bike, however the controller is not listed by make and model, be careful when installing it because the wiring patterns going to the connectors may be different than that of the original controller. Double check the wiring to make sure that it is correct before installing the new controller. If the connectors are correct but the wiring going to the connectors are incorrect the pins can be removed and installed in different locations on the connector.
• Sometimes the brake switch becomes defective and locks into the on position which makes the controller turn off the motor. If the scooter works after disconnecting the brake switch then the brake switch is defective.

Controller Installation Tips:

1. Before replacing the controller make sure that the key switch or power switch is in the off position.

2. Disconnect the battery pack from the controller first when removing a controller, and connect the battery pack to the controller last when installing a controller.

3. Hang or block the rear wheel off the ground, or remove the chain or belt from the motor before connecting the battery pack to the controller. Sometimes due to damaged or incorrect wiring or faulty electrical components the rear wheel might spin uncontrollably when making the final wiring connection to the battery pack.

4. Do not short-circuit the battery terminals or wiring harness connector pins and make sure the batteries fit snug into place and that all of the wiring and connectors are in good serviceable condition.
