Battery
For battery related information, see Section 2.
RPM Limiter
NOTE: The ATV is equipped with a CDI unit that
retards ignition timing when maximum RPM is
approached. When the RPM limiter is activated, it
could be misinterpreted as a high-speed misfire.
Testing Electrical
Components
All of the electrical tests should be made using the
Fluke Model 73 Multimeter (p/n 0644-191) and
when testing peak voltage, the Peak Voltage Read-
ing Adapter (p/n 0644-307) must be used. If any
other type of meter is used, readings may vary due
to internal circuitry. When troubleshooting a spe-
cific component, always verify first that the fuse(s)
are good, that the bulb(s) are good, that the connec-
tions are clean and tight, that the battery is fully
charged, and that all appropriate switches are acti-
vated.
NOTE: For absolute accuracy, all tests should be
made at room temperature of approximately 68° F.
Brakelight Switch
(Auxiliary)
The switch connector is the two-prong white con-
nector on the right side of the engine directly above
the switch.
NOTE: The ignition switch must be in the ON
position.
VOLTAGE
(Wiring Harness Side)
1. Set the meter selector to the DC Voltage posi-
tion.
2. Connect the red tester to the brown/blue wire;
then connect the black tester lead to ground.
3. The meter must show battery voltage.
NOTE: If the meter shows no battery voltage,
troubleshoot the battery, fuse, switch, or the main
wiring harness.
NOTE: If the meter shows battery voltage, the
main wiring harness is good; proceed to test the
switch/component, the connector, and the switch
wiring harness for resistance.
