The 50 Amp Dynamic R-Series V3.02 controller for the Go-Go Sport (S73/S74) mobility scooters is the "electronic brain" of a scooter's operating system. Even with no moving parts, a controller can still wear out due to improper charging, high humidity, or other corrosive factors.
Note: Dynamic makes their R-series controllers for many mobility brands and models however they are not interchangeable. This unit has been programmed specifically for the Go-Go Sport (S73/S74), and it may not be fully functional on any other mobility scooter.
