8.13 THE OPERATION PRINCIPLE OF THE ELECTRIC 4WD SHIFT

(Fig 1)
1, The rider shifts 2WD to 4WD by the Switch on handlebar.
2. The Switch gives signal to Controller.
3, The controller gives power to the Shift Motor.
4, If the Splined Dog (Fig 2) is in right position, 4WD will engage immediately. This information
will be given to the Sensor by the Magneto on the Selector Plate, and then to the Controller.
Controller lights the 4WD indicator.
5. If the Splined Dog is not in right position, 4WD won't engage, this information will be given to
the Sensor by the Magneto on the Selector Plate, and then to the Controller. The controller will
try to drive the Shift Motor several times in 1 min.
During this time, the 4WD indicator is not on, this requires the rider to back or move (ride) the
ATV a little to allow the Dog change position for engagement. ( See owner's manual or decal).
If the rider doesn't do as the owner's manual, after 1 min, the buzzer comes on and 4WD
indicator blinks, remind the rider to re-shift.
Shift from 4WD to 2WD is same as above.
