Speed Sensor; Ignition Switch - Arctic Cat 2009 366 Service Manual

Speed Sensor

1. Set the meter selector to the DC Voltage position.
2. With appropriate needle adapters on the meter
leads, connect the red tester lead to the voltage
lead (V); then connect the black tester lead to the
ground lead (G).
3. Turn the ignition switch to the ON position.
4. The meter must show greater than 5.0 volts.
5. Leave the black tester lead connected; then con-
nect the red tester lead to the signal lead pin (S).
6. Slowly move the ATV forward or backward; the
meter must show 0 and 6 volts alternately.
NOTE: If the sensor tests are within specifica-
tions, the speedometer must be replaced (see Sec-
tion 9).
To replace a speed sensor, use the following proce-
dure.
1. Disconnect the three-wire connector from the
speed sensor; then remove the cap screw securing
the sensor to the sensor housing.
2. Remove the sensor from the sensor housing
accounting for an O-ring.
