Here is a part for a relatively rare scooter. This throttle potentiometer for the Invacare Zoom (HMV 300) / Buzz (HMV R17) is the perfect replacement for a damaged or missing potentiometer on your Invacare Zoom (HMV 300) or Buzz (HMV R17).
Our throttle pot comes with the harness, spring, and "wig-wag" lever included.
The throttle potentiometer (or "pot") is also known as the engager or throttle switch. Faulty throttle potentiometers can lead to "jerky" motion while throttling, or no motion at all.
