
NOTE: Battery voltage will be indicated from only
one side of the fuse holder connector terminal; the
other side will show no voltage.

NOTE: When testing the HI fuse holder, the head-
light dimmer switch must be in the HI position; when
testing the LIGHTS fuse holder, the headlight dim-
mer switch can be in either position.

NOTE: If the meter shows no battery voltage, trou-
bleshoot the battery, switches, distribution module, or
the main wiring harness.
FUSES

NOTE: To remove a fuse, compress the locking tabs
on either side of the fuse case and lift out.
3411-968
1. Set the meter selector to the OHMS position.
2. Connect the red tester lead to one spade end of the
fuse; then connect the black tester lead to the other
spade end.
3. The meter must show less than 1 ohm resistance. If
the meter reads open, replace the fuse.

NOTE: Make sure the fuses are returned to their
proper position according to amperage. Refer to the
fuse block decal for fuse placement.
RELAYS
The 4-pin relays are identical plug-in type and can be
checked by switching relay positions.

NOTE: The module and wiring harness are not a
serviceable components and must be replaced as an
assembly.
EFI Sensors/Components
FUEL INJECTOR
Voltage
Remove the connector from the fuel injector. Place the
red meter lead to the orange wire and black meter lead to
ground. With the ignition switch in the on position the
meter must read battery voltage.
Resistance
With the connector still removed from the injector, place
the red meter lead to either terminal; then connect the
black tester lead to the other terminal. Reading is typi-
cally 12 ohms.

NOTE: If voltage is not present, troubleshoot the
battery, connector pins, wiring harness, fuses, or
relay. If resistance is not present or largely out of
specification, replace the injector.
CRANKSHAFT POSITION (CKP)
SENSOR
Resistance
1. Set the meter selector to the OHMS position and test
as follows.
2. The meter reading must be within specification.
AC Voltage

NOTE: The battery must be at full charge for these
tests.
1. Set the meter selector to the AC Voltage position and
test as follows.
2. Crank the engine over using the electric starter. The
meter reading must be within specification.
OXYGEN (O2) SENSOR
The sensor is located in the exhaust pipe.
1. On the right side of the ATV, unplug the connector.
CAUTION
Always replace a blown fuse with a fuse of the same
type and rating.
CAUTION
Always disconnect the battery when performing resis-
tance tests to avoid damaging the multimeter.
Component data can be tested using the CATT II. Utilize
the Test screen.
