Battery Charging Chart (Constant-Current Charger)
Battery Voltage Charge
(DC) State
12.5 or more 100%
12.2-12.4 75%-99%
12.0-12.2 50%-74%
11.0-11.9 25%-49%
11.5 or less 0-24%
 NOTE: If the battery voltage is 11.5 DC Volts or less,
some chargers may "cut off" and fail to charge. If this
occurs, connect a fully charged booster battery in
parallel (positive to positive and negative to negative)
for a short period of time with the charger connected.
After 10-15 minutes, disconnect the booster battery
leaving the charger connected and the charger
should continue to charge. If the charger "cuts off,"
replace the battery.
6. After charging the battery for the specified time,
remove the battery charger and allow the battery to
sit for 1-2 hours.
7. Connect the multimeter and test the battery voltage.
The meter should read 12.5 or more DC Volts. If the
voltage is as specified, the battery is ready for ser-
vice.
 NOTE: If voltage in step 7 is below specifications,
charge the battery an additional 1-5 hours; then
retest.
8. Place the battery in the battery case; then coat the
battery posts and cable ends with a light coat of
multi-purpose grease.
CAUTION
Before installing the battery, make sure the ignition
switch is in the OFF position.
9. Connect the battery cables (positive cable first); then
install the battery case access cover.
CAUTION
Connecting cables in reverse (positive to negative and
negative to positive) can cause serious damage to the
electrical system.

RPM Limiter

 NOTE: The ATV is equipped with an ECU 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 or Fluke Model 77 Multimeter and
when testing peak voltage, the Peak Voltage Reading
Adapter must be used. If any other type of meter is used,
readings may vary due to internal circuitry. When trou-
bleshooting a specific component, always verify first that
the fuse(s) are good, that the bulb(s) are good, that the
connections are clean and tight, that the battery is fully
charged, and that all appropriate switches are activated.
 NOTE: For absolute accuracy, all tests should be
made at room temperature of 68° F.
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 wire; then con-
nect the black tester lead to ground.
3. The meter must show battery voltage.
 NOTE: If the meter shows no battery voltage, trou-
bleshoot the battery, fuse, receptacle, connector, or
the main wiring harness.

Brakelight Switch

(Pressure)
The brakelight switch is located on the top of the brake
master cylinder and is pressure activated by the hand
brake or the brake pedal. This switch also activates the
start-in-gear (SIG) relay in the power distribution module
(PDM).
 NOTE: The ignition switch must be in the ON posi-
tion.
VOLTAGE
(Wiring Harness Side)
1. Set the meter selector to the DC Voltage position.
2. Connect the red tester to the brown/black wire; then
connect the black tester lead to ground.
3. The meter must show battery voltage.
