The an91'e sensor, instaUed on the control motor, converts the direction of rotationrotating angle and rotating speed of the sub-gearshihs spindle into voltage change and speed change and outputs them to the Electronic Contro Unit
Gear Position Switch
The' gear positi on switch, insta lled inside the rea cran:kccase, controls tba starta(' relay switch and also sends Reverse, Neutral 1stand '5th signa l:s to the Etectronic Control UnitSpeed Sensor The speed sensor, installed on the rear crankcase, sends vehicle speed signal both to the oombioation meter and the Electronic Control Unit
DESCRIPTION OF MAJOR COMPONENTS
Angle Sensor
SUB-GEARSHIFT SPINDLE
The angle senSor shaft is connected to the end of the sub-gearshih spindleIt converts the: direction of rotationrotatingangle and rotatin speed of the sub-gears.hlft spind le into voltage change and speed change and then outputs these signals the Erectronic ContTol UoitThe rotation of the ang le sensor shaft changes variable resistance value, thereby changing the output voltag:e to the Electronic Control Unit from the ang:le senSOrTh'8 Electronic Controli Unit detects whether the gear is shifted down or up during the voltage change
