neutral switch and sidestand switch as described in
this chapter.
Precautions
Damage to the semiconductors in the system may
occur if the following precautions are not observed.

1. Never connect the battery backwards. If the bat-
tery polarity is incorrect, the voltage regulator, al-
ternator and ignitor unit will be damaged.
2. Do not disconnect the battery while the engine is
running.
3. Keep all connections between the various units
clean and tight. Make sure the wiring connectors are
firmly pushed together.
4. Do not substitute another type of ignition coil or
battery.
5. Each solid-state unit is mounted on a rubber vi-
bration isolator. Make sure the isolators are in place
when replacing any units.
SPARK PLUG CAP
Resistance
1. Disconnect the spark plug cap from the spark
plug.
2. Measure the resistance between each end of the
cap as shown in Figure 9.
3. Replace the spark plug cap if the resistance ex-
ceeds the specification in Table 1.
4. Repeat this test for the other spark plug cap.

IGNITION COIL

The front cylinder ignition coil is mounted on the
left side of the frame; the rear cylinder ignition coil
sits on the right side. Occasionally check to see that
the coils are mounted securely.
Resistance Test
Test the ignition coils at a minimum temperature
of 20° C (68° F).
