Replace your faulty potentiometer with this Drive Medical throttle potentiometer for the Spitfire EX (S1320 & S1420). The throttle pot is sometimes called the engager or throttle switch. If your scooter has a faulty throttle potentiometer, it can cause a jerky motion while the lever is being pressed, and eventually no forward or backward motion at all. Before your scooter totally stops running due to a bad throttle pot, get a new one from Monster Scooter Parts and keep on scooting.

Please note that this throttle assembly does not fit on the Drive Medical Spitfire Scout or Spitfire Scout DLX scooters.

Drive calles this potentiometer (or "throttle pot") their 2nd generation Spitfire throttle. It is essentially the same 1st generation throttle that was used on the ActiveCare Spitfire scooters, but it uses a more ergonomic and user-friendly "wig-wag" lever. So much the same in fact that this Drive Medical throttle assembly easily retrofits on the older 1st generation ActiveCare models.
