Speed Sensor - Arctic Cat 2011 425 Service Manual

RESISTANCE
CAUTION
Always disconnect the battery when performing resis-
tance tests to avoid damaging the multimeter.
 NOTE: For these tests, the meter selector should be
set to the OHMS position and the primary wire should
be disconnected.
Primary Winding
1. Connect the red tester lead to either terminal; then
connect the black tester lead to the other terminal.
2. The meter reading must be within specification.
Secondary Winding
1. Remove the plug cap from the high tension lead;
then connect the red tester lead to the high tension
lead.
2. Connect the black tester lead to ground.
3. The meter reading must be within specification.
 NOTE: If the meter does not show as specified,
replace ignition coil.
Spark Plug Cap
1. Connect the red tester lead to one end of the cap;
then connect the black tester lead to the other end of
the cap.
2. The meter reading must be within specification.
 NOTE: If the meter does not read as specified,
replace the spark plug cap.
Primary Voltage - ECU
1. Set the meter selector to the DC Voltage position;
then disconnect the two wires from the coil.
2. Connect the red tester lead to the orange wire and the
black tester lead to the blue/white wire.
3. Turn the ignition switch to the ON position. The
meter must show battery voltage.

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 connect
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 specifications,
the speedometer must be replaced (see Steer-
ing/Frame/Controls section).
To replace a speed sensor, use the following procedure.
1. Disconnect the three-wire connector from the speed
sensor; then remove the cap screw securing the sen-
sor to the sensor housing.
2. Remove the sensor from the sensor housing account-
ing for an O-ring.

3. Install the new speed sensor into the housing with
new O-ring lightly coated with multi-purpose grease;
then secure the sensor with the cap screw (threads
coated with blue Loctite #242). Tighten securely.
