Power Distribution Module (Pdm); Ignition Coil - Arctic Cat 2014 XC 450 Service Manual

 NOTE: If the meter shows no battery voltage, trou-
bleshoot the battery, fuse, relay, motor, or the main
wiring harness.
 NOTE: If the meter shows battery voltage, the main
wiring harness is good. The connector should be
checked for resistance.
RESISTANCE (Fan Motor Connector)
1. Set the meter selector to the OHMS position.
2. Connect the red tester lead to the red wire; then con-
nect the black tester lead to the black wire.
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)
A number of fuses and relays 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 related 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.
86
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.
Primary Winding
KC466A
1. Connect the red tester lead to either terminal; then
connect the black tester lead to the other terminal.
2. The meter reading must be within specification.
Secondary Winding
1. Remove the plug cap from the high tension lead; then
connect the red tester lead to the high tension lead.
2. Connect the black tester lead to ground.
