6. Slowly move the ATV forward or backward; the
meter must show 0 and 6 DC volts alternately.
To replace a speed sensor, use the following procedure.
1. Disconnect the three-wire connector from the speed
sensor harness or from the speed sensor; then remove
the Allen-head cap screw securing the sensor 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 Allen-head cap screw
(threads coated with blue Loctite #242). Tighten
securely.

Ignition Switch
The connector is a four-wire one. To access the connec-
tor, the cover must be removed.
VOLTAGE
NOTE: Perform this test on the lower side of the
connector.
1. Set the meter selector to the DC Voltage position.
2. Connect the red meter lead to the red wire; then con-
nect the black meter lead to battery ground.
3. Meter must show battery voltage.
NOTE: If the meter shows no battery voltage, trou-
bleshoot the battery or the main wiring harness.
RESISTANCE
NOTE: Perform this test on the upper side of the
connector.
1. Turn the ignition switch to the ON position.
2. Set the meter selector to the OHMS position.
3. Connect the red tester lead to the red wire; then con-
nect the black tester lead to the red/black wire.
4. The meter must show less than 1 ohm.
5. Turn the ignition switch to the LIGHTS position.
6. Connect the red tester lead to the red wire; then con-
nect the black tester lead to the red/black wire.
7. The meter must show less than 1 ohm.
8. Connect the red tester lead to the red wire; then con-
nect the black tester lead to the gray wire.
9. The meter must show less than 1 ohm.
10. With the switch in the OFF position, connect the red
tester lead to the red wire and the black tester lead to
each of the remaining wires. The meter must show
an open circuit on all wires.
11. Connect the red tester lead to the red wire and the
black tester lead to the brown wire. With the switch
in the ON position, the meter must show 980-1020
ohms.
NOTE: If the meter shows more than 1 ohm of resis-
tance, troubleshoot or replace the switch/component,
the connector, or the switch wiring harness.
Handlebar Control
Switches
The connector is the yellow one next to the steering post.
To access the connector, the steering post cover and the
right-side fender splash shield must be removed (see
Steering/Frame/Controls).
NOTE: These tests should be made on the top side
of the connector.
RESISTANCE (HI Beam)
1. Set the meter selector to the OHMS position.
2. Connect the red tester lead to the yellow wire; then
connect the black tester lead to the gray wire.
3. With the dimmer switch in the HI position, the meter
must show less than 1 ohm.
NOTE: If the meter shows more than 1 ohm of resis-
tance, troubleshoot or replace the switch/component,
the connector, or the switch wiring harness.
CAUTION
Always disconnect the battery when performing resis-
tance tests to avoid damaging the multimeter.
