Ignition Coil; Speed Sensor - Arctic Cat 2012 350 Service Manual

RELAYS
The relays are identical plug-in type located on the power
distribution module. Relay function can be checked by
switching relay positions. The relays are interchangeable.
 NOTE: The module and wiring harness are not a service-
able component and must be replaced as an assembly.

Ignition Coil

The ignition coil is on the frame above the engine. To
access the coil, the left side panel must be removed.
RESISTANCE
CAUTION
Always disconnect the battery when performing resis-
tance tests to avoid damaging the multimeter.
 NOTE: For these tests, the meter selector should be
set to the OHMS position and the primary wire should
be disconnected.
Primary Winding
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.
3. The meter reading must be within specification.
 NOTE: If the meter does not show as specified,
replace ignition coil.
Spark Plug Cap
1. Connect the red tester lead to one end of the cap;
then connect the black tester lead to the other end of
the cap.
2. The meter reading must be within specification.
 NOTE: If the meter does not read as specified,
replace the spark plug cap.
82
PEAK VOLTAGE
 NOTE: All of the peak voltage tests should be made
using the Fluke Model 73 Multimeter or Fluke Model
77 Multimeter with Peak Voltage Reading Adapter. If
any other type of tester is used, readings may vary
due to internal circuitry.
 NOTE: The battery must be at full charge for these
tests.
Primary/CDI
 NOTE: The CDI is located on the electrical tray in
front of the steering shaft.
1. Set the meter selector to the DC Voltage position;
then disconnect the black/yellow and black primary
wires from the coil.
2. Connect the red tester lead to the black/yellow wire;
then connect the black tester lead to the black wire.
3. Crank the engine over using the electric starter.
4. The meter reading must be within specification.

Speed Sensor

1. Set the meter selector to the DC Voltage position.
2. With appropriate needle adapters on the meter leads,
AR603D
connect the red tester lead to the voltage lead (V);
then connect the black tester lead to the ground lead
(G).
