NOTE: If battery voltage is not shown and the head-
lights are illuminated, inspect the three-wire connec-
tor in the left-rear canopy tube at the juncture of the
canopy tube and lower frame. If battery voltage is
shown on the meter, replace the LED.
VOLTAGE (Brakelight)
NOTE: Perform this test at the socket end of the tail-
light/brakelight harness (pigtail). The ignition switch
must be in the ON position.
1. Set the meter selector to the DC Voltage position.
2. Connect the red tester lead to the red/blue wire; then
connect the black tester lead to the black wire.
3. With the brake applied, the meter must show battery
voltage.
NOTE: If the meter shows no voltage, inspect the 10
amp ignition (IGN) fuse, brakelight switch, wiring har-
ness, or connectors.
Ignition Timing
The ignition timing cannot be adjusted; however, verifying
ignition timing can aid in troubleshooting other compo-
nents. To verify ignition timing, use the following proce-
dure.
NOTE: To check ignition timing, the seats and cen-
ter console must be removed.
1. Attach the Timing Light to the spark plug high tension
lead; then remove the timing inspection plug from the
left-side crankcase cover.
2. Start the engine and using the RPM function on the
speedometer/tachometer, run at 1500 RPM; ignition
timing should be 10° BTDC.
3. Install the timing inspection plug.
If ignition timing cannot be verified, the rotor may be
damaged, the key may be sheared, the trigger coil bracket
may be bent or damaged, or the ECM may be faulty.
Tilt Sensor
The tilt sensor is located in the center console above the
forward driveline coupler. The seats and center console
must be removed to access the sensor.
SUPPLY VOLTAGE
1. Disconnect the three-wire connector from the sensor;
then select DC Voltage on the multimeter and connect
the red tester lead to the orange wire (C) and the pink
tester lead to the pink wire (A).
CD706C
2. Turn the ignition switch to the ON position. The mul-
timeter should read battery voltage. If battery voltage
is not indicated, check the 30-amp fuse, wiring har-
ness, or the ignition switch.
3. Remove the red tester lead and connect to the blue/
brown wire (B). The multimeter should read approxi-
mately 2.5 DC volts. If the specified voltage is not
indicated, check wire connections at the ECM or sub-
stitute another ECM to verify the test.
OUTPUT VOLTAGE
NOTE: Needle adapters will be required on the mul-
timeter leads as the following tests are made with the
sensor connected.
1. Connect the three-wire plug to the sensor; then
remove the right-side mounting screw securing the
sensor to the frame.
2. Install the needle adapters to the multimeter leads;
then select DC Voltage on the multimeter.
3. Connect the red tester lead to the blue/brown wire (B)
and the black tester lead to the pink/black wire (A);
then turn the ignition switch ON and observe the
meter. The meter should read 0.8-3.0 DC volts.
CD705B
4. Tilt the sensor 60° or more to the left and right observ-
ing the meter. The meter should read 4.0-8.0 DC volts
after approximately one second in the tilted position.
If the meter readings are not as specified, the tilt sen-
sor is defective.
! WARNING
Incorrect installation of the tilt sensor could cause sud-
den loss of engine power which could result in loss of
vehicle control resulting in injury or death.
CAUTION
Do not drop the tilt sensor as shock can damage the
internal mechanism.
