Ignition Coil; Power Distribution Module (Pdm); Relays - Arctic Cat 450 XC 2011 Service Manual

3. The meter must show less than 1 ohm.
 NOTE: If the meter shows more than 1 ohm of resis-
tance, troubleshoot or replace the switch/component,
the connector, or the switch wiring harness.
 NOTE: To determine if the fan motor is good, con-
nect the blue wire from the fan connector to the posi-
tive side of a 12 volt DC power supply; then connect
the black wire from the fan connector to the negative
side. The fan should operate.
! WARNING
Care should be taken to keep clear of the fan blades.
Power Distribution
Module (PDM)
The fuses are located in the power distribution module in
front of the steering post under the radiator/electrical
access panel.
If there is any type of electrical system failure, always
check the fuses first.
 NOTE: To remove a fuse, compress the locking tabs
on either end of the PDM cover and lift off; then
remove the applicable fuse.
CAUTION
Always replace a blown fuse with a fuse of the same
type and rating.

RELAYS

The relays are identical plug-in type located on the PDM.
Relay function can be checked by switching relay posi-
tions. The relays are interchangeable.
 NOTE: The PDM and wiring harness are not a ser-
viceable components and must be replaced as an
assembly.
The ignition coil is on the frame above the radiator. To
access the coil, the radiator/electrical access panel must
be removed.
RESISTANCE
 NOTE: For these tests, the meter selector must be
set to the OHMS position and the primary plug dis-
connected.
