NOTE: Not using a battery charger with the
proper float maintenance will damage the battery if
connected over extended periods.
Charging
NOTE: Arctic Cat recommends the use of the
CTEK Multi US 800 or the CTEK Multi US 3300 for
battery maintenance charging.
1. Be sure the battery and terminals have been cleaned
with a baking soda and water solution.
NOTE: The sealing strip should NOT be removed
and NO fluid should be added.
2. Be sure the charger and battery are in a well-venti-
lated area. Be sure the charger is unplugged from the
110-volt electrical outlet.
3. Connect the red terminal lead from the charger to the
positive terminal of the battery; then connect the
black terminal lead of the charger to the negative ter-
minal of the battery.
4. Plug the charger into a 110-volt electrical outlet.
5. By pushing the Mode button (A) on the left side of
the charger, select the Normal Charge Icon (E). The
Normal Charge Indicator (C) should illuminate on
the upper left portion of the charger.
6. The battery will charge to 95% of its capacity at
which time the Maintenance Charge Indicator (D)
will illuminate.
NOTE: For optimal charge and performance,
leave the charger connected to the battery for a
minimum 1 hour after the Maintenance Charge
Indicator (D) illuminates. If the battery becomes
hot to the touch, stop charging. Resume after it
has cooled.
7. Once the battery has reached full charge, unplug the
charger from the 110-volt electrical outlet.
NOTE: If, after charging, the battery does not per-
form to operator expectations, bring the battery to
an authorized Arctic Cat dealer for further trouble-
shooting.

 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
3300A
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.

Main 30-Amp Fuse

The electrical system is protected by a 30-amp main fuse
incorporated within the starter relay under the battery
cover. If all electrical accessories/components fail to
operate, always check this main fuse first.
Accessory Receptacle/
 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.
