VOLTAGE
„
NOTE: Perform this test in turn on the main har-
ness side of the connectors. Also, the ignition
switch must be in the LIGHTS position and the
engine must be running.
1. Set the meter selector to the DC Voltage position.
2. Connect the red tester lead to the green wire; then
connect the black tester lead to the white wire.
3. With the dimmer switch in the LO position (LO
beam), the meter must show battery voltage.
4. Connect the red tester lead to the blue wire. With
the dimmer switch in the HI position (HI beam),
the meter must show battery voltage.
„
NOTE: If battery voltage is not shown in any test,
inspect the fuses, battery, main wiring harness,
connectors, or the left handlebar switch.

Ignition Timing
The ignition timing cannot be adjusted; however, veri-
fying ignition timing can aid in troubleshooting other
components. To verify ignition timing, use the follow-
ing procedure.
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. Using the Tachometer, start the engine and run at
1000 RPM; ignition timing should be 5° BTDC
(“F” mark).
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 CDI unit may
be faulty.
