4. The meter must show less than 1 ohm.

5. Turn the ignition switch to the LIGHTS position.

6. Connect either tester lead to pin A; then connect the

other tester lead to pin B.

7. The meter must show less than 1 ohm.

8. Connect either tester lead to pin C; then connect the

other tester lead to pin D.

9. The meter must show less than 1 ohm.

10. With the switch in the OFF position, connect the red

tester lead and the black tester lead to each of the
remaining pins. The meter must show an open circuit
on all pins.



NOTE: If the meter shows more than 1 ohm of resis-

tance, replace the switch.

Ignition Coil

The ignition coil is on the frame above the engine. To
access the coil, the right side panel must be removed.

VOLTAGE
Primary Coil

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 white/blue wire.

3. Turn the ignition switch to the ON position. The

meter must show battery voltage.

Secondary Coil

1. Connect the primary ignition coil connector. Remove

the spark plug cap from the spark plug.

2. Connect the spark plug cap to Ignition Test Plug or

other suitable tool; then ground the tool away from
the spark plug hole. While turning the engine over,
check for sufficient spark.

RESISTANCE



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.



NOTE: Secondary coil resistance checks are not rec-

ommended. An internal diode in the coil prevents
accurate secondary resistance measurements.

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.

AR603D

2. The meter reading must be within specification.



NOTE: If the meter does not read as specified,

replace the spark plug cap.

Ignition Timing

The ignition timing cannot be adjusted; however, verify-
ing ignition timing can aid in troubleshooting other com-
ponents. To verify ignition timing, use the following
procedure.

1. Attach the Timing Light to the spark plug high ten-

sion lead; then remove the timing inspection plug
from the left-side crankcase cover.

2. Using the Tachometer, start the engine and 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/CKP
sensor bracket may be bent or damaged, or the ECM may
be faulty.

Accessory

Receptacle/Connector



NOTE: This test procedure is for either the recepta-

cle or the connector.

VOLTAGE

1. Turn the ignition switch to the ON position; then set

the meter selector to the DC Voltage position.

2. Connect the red tester lead to the red/white wire or

the positive connector; then connect the black tester
lead to ground.

3. The meter must show battery voltage.
