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
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 black
tester lead to the black wire (A).
CD706A
2. Turn the ignition switch to the ON position. The multi-
meter should read battery voltage. If battery voltage is
not indicated, check the 30-amp fuse, wiring harness,
or the ignition switch.
3. Remove the red tester lead and connect to the
blue/brown wire (B). The multimeter should read
approximately 2.5 DC volts. If the specified voltage is
not indicated, check wire connections at the ECM or
substitute another ECM to verify the test.
CD706B
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 rear frame.
CD707
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 black/yellow 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
observing 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 sensor 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.
