 NOTE: If the meter does not read as specified,
replace the ignition coil.
SPARK PLUG CAP RESISTANCE
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.
2. The meter must read 4725-5775 ohms.
 NOTE: If the meter does not read as specified,
replace the spark plug cap.

Ignition Switch

The connector is accessible below the front fender panel
in front of the steering post.
VOLTAGE
 NOTE: Perform this test on the harness 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 a suitable ground.
3. Meter must read battery voltage.
 NOTE: If the meter reads no battery voltage, trouble-
shoot the battery, fuse, or the main wiring harness.
RESISTANCE
CAUTION
Always disconnect the battery when performing resis-
tance tests to avoid damaging the multimeter.
 NOTE: Perform this test on the switch 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 green/yellow wire.
4. The meter must read less than 1 ohm.
5. Connect the red tester lead to the red wire; then con-
nect the black tester lead to the green wire.
6. The meter must read less than 1 ohm.
7. 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 read an
open circuit on both wires.
 NOTE: If the meter reads more than 1 ohm of resis-
tance, troubleshoot or replace the switch/ compo-
nent, the connector, or the switch wiring harness.

Handlebar Control
The connector is in front of the steering post. The con-
nector is accessible beneath the front fender.
 NOTE: These tests should be made on the switch
side of the connector.
Always disconnect the battery when performing resis-
tance tests to avoid damaging the multimeter.
RESISTANCE (Starter Button)
1. Set the meter selector to the OHMS position.
2. Connect the red tester lead to the yellow/white wire;
then connect the black tester lead to the green wire.
3. With the starter button depressed, the meter must
read less than 1 ohm.
4. With the starter button released, the meter must read
an open circuit.
 NOTE: If the meter does not read as specified,
replace the switch/component, connector, or switch
harness.
RESISTANCE (Emergency Stop)
1. Set the meter selector to the OHMS position.
2. Connect the red tester lead to the blue/yellow wire;
then connect the black tester lead to the green wire.
3. With the switch in the OFF position, the meter must
read an open circuit.
4. With the switch in the RUN position, the meter must
read less than 1 ohm.
 NOTE: If the meter reads more than 1 ohm of resis-
tance, troubleshoot or replace the switch/component,
the connector, or the switch wiring harness.
