NOTES

    1. The red Motor and Battery wires are attached together inside of the controller so it does not matter which one goes to the Motor or Battery.
    2. When connecting the controller to the battery a spark may occur and this is normal.
    3. Make the battery connection your last connection.
    4. This controller uses a standard Hall Effect (3 - Wire) throttle.
    5. The brake lever switch connection is optional. The controller will operate with nothing attached to the brake lever switch. When the brake lever connector's black and yellow wires are contacted together the motor will turn off and then the motor will turn on again when the black and yellow wires are not contacting each other.
