Abstract: The present invention describes an adjustable speedometer/odometer to accommodate various vehicle drive configurations such as a variety of vehicle tire size and rear axle ratios. The range adjustment is made at the factory or by service personnel, and is implemented by a plurality of switches, insuring a positive selection of the desired range value, thereby eliminating the need for calibration. The conventional mechanical speedometer/odometer and speedometer cable are replaced by a signal transducer mounted on the transmission, and an electronic speedometer unit. The transducer sends signal pulses to the electronic speedometer unit that displays the vehicle speed and distance travelled, by a moving-magnet meter and an incremental counter, respectively. In addition, the range of the speedometer/odometer is switched to accommodate a dual-axle ratio differential according to a signal from an axle mounted switch.
