Ignition Coils; Efi Sensors/Components - Arctic Cat Wildcar Trail Service Manual

This vehicle uses automotive-style (see-through) fuses. The
fuses can be visually inspected; replace fuse if link is open.
CAUTION
Always replace a blown fuse with a fuse of the same
type and rating.
 NOTE: Make sure the fuses are returned to their
proper position according to amperage. Refer to the
amperage listed under each fuse on the power distri-
bution module.

Ignition Coils

The ignition coils are mounted to the upper frame above
the engine.
VOLTAGE (Primary Coil)
1. Set the meter selector to the DC Voltage position; then
disconnect the connector from the coil to be tested.
2. Using MaxiClips, connect the red tester lead to the
orange wire and the black tester lead to ground.
3. Turn the ignition switch to the ON position. The meter
must show battery voltage.
4. Repeat for the other coil.
RESISTANCE (Primary Winding)
CAUTION
Always disconnect the battery when performing resis-
tance tests to avoid damaging the multimeter.
 NOTE: For this test, the meter selector should be
set to the OHMS position.
92
1. Disconnect the coil connector. Connect the red tester
lead to one coil terminal; then connect the black tester
lead to the other coil terminal.
2. Resistance must be less than 1 ohm.
 NOTE: If the meter does not show as specified,
replace ignition coil.
 NOTE: Secondary coil resistance checks are not
recommended. An internal diode in the coil prevents
3411-964
accurate secondary resistance measurements.
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 must show 5000 ohms.
 NOTE: If the meter does not show as specified,
replace the spark plug cap.
