7. If the meter reads less than specified voltage,

charge the battery using the following guidelines.

A. When using an automatic battery charger,

always follow the charger manufacturer’s

instructions.

B. When using a constant-current battery charger,

use the following Battery Charging Chart.



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 bat-
tery.

8. After charging the battery for the specified time,

remove the battery charger and allow the battery to

sit for 1-2 hours.

9. Connect the multimeter and test the battery volt-

age. The meter should read 12.5 or more DC Volts.

If the voltage is as specified, the battery is ready

for service.



NOTE: If voltage in step 9 is below specifications,

charge the battery an additional 1-5 hours; then
retest. Recheck electrolyte level (lead-acid battery)
and the battery is ready for service.

10. Place the battery in the battery compartment; then

coat the battery posts and cable ends with a light

coat of multi-purpose grease.

11. Connect the battery cables (positive cable first);

then install the battery hold-down.



NOTE: Arctic Cat highly recommends all ATV bat-

teries be connected to a maintenance charger dur-
ing storage or any extended period of non-use.
This charger MUST have an automatic float, stor-
age-safe, or pulse maintenance mode to avoid bat-
tery damage due to long-term overcharging. To
connect the maintenance charger, use any of the
following procedures.

A. Remove the battery cover; then connect the

charger leads (positive cable first) directly to

the battery.

B. Locate the rear accessory connector and con-

nect the charger leads (positive cable first)

directly to the connector.

C. Using an appropriate adapter, connect the char-

ger to any DC power outlet.

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 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 troubleshooting a

specific 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 68° F.

CAUTION

Never exceed the standard charging rate.

! WARNING

An overheated battery could explode causing severe
injury or death. Always monitor charging times and
charge rates carefully. Stop charging if the battery
becomes very warm to the touch. Allow it to cool
before resuming charging.
