If your Izip i200 Scooter is not working, replacing the controller is almost always the solution. This 24 volt 25 amp controller will work specifically with your Schwinn, Ezip & Izip 200 Series Electric Scooters. The throttle connector on this controller is a black 2 pin connector. If you receive a contorller with a yellow wire, and do not have a connector on your scooter for it, do not worry as it does not need to be used. It is a charge inhibit wire for later models of the same scooter.
