Ignition Timing - Arctic Cat 1000 XT 2014 Service Manual

The ECM is rarely the cause for electrical problems; how-
ever, if the ECM is suspected, substitute another ECM of the
same part number to verify the suspected one is defective.
Codes can be cleared by following the procedures located
in CF329 in this section.
Regulator/Rectifier
The regulator/rectifier is located under the rear rack and
rear fenders.
TESTING
1. Start engine and warm up to normal operating
temperature; then connect a multimeter to the bat-
tery as follows.
2. Select the DC Voltage position; then connect the
red tester lead to the positive battery post and the
black tester lead to the negative battery post.
3. Start the engine and slowly increase RPM. The
voltage should increase with the engine RPM to a
maximum of 15.5 DC volts.

NOTE: If voltage rises above 15.5 DC volts, the reg-
ulator is faulty or a battery connection is loose or
corroded. Clean and tighten battery connections or
replace the regulator/rectifier. If voltage does not rise,
see Stator Coil/Crankshaft Position (CKP) Sensor -
Voltage in this section. If charging coil voltage is nor-
mal, replace the regulator/rectifier.
Headlights
The connectors are the four 2-prong ones plugged into
the headlight bulbs (two on each side).
VOLTAGE

NOTE: Perform this test in turn on the main harness
side of all four connectors. Also, the ignition switch
must be in the LIGHTS position.

NOTE: The LO beam is the outside bulb, and the HI
beam is the inside bulb.
1. Set the meter selector to the DC Voltage position.
2. Connect the red tester lead to one wire; then con-
nect the black tester lead to the other wire.
3. With the dimmer switch in the LO position, test
the two outside connectors (LO beam). The meter
must show battery voltage.
4. With the dimmer switch in the HI position, test the
two inside connectors (HI beam). The meter must
show battery voltage.
110

NOTE: If battery voltage is not shown in any test,
inspect the LIGHTS fuse, battery, main wiring har-
ness, connectors, or the left handlebar switch.
Taillight - Brakelight
The connector is the 3-prong one located under the rear
fender assembly.
VOLTAGE (Taillight)

NOTE: Perform this test on the main harness side of
the connector. Also, the ignition switch should be in
the LIGHTS position.
1. Set the meter selector to the DC Voltage position.
2. Connect the red tester lead to the white wire; then
connect the black tester lead to the black wire.
3. With the ignition key in the LIGHTS position, the
meter must show battery voltage.

NOTE: If the meter shows no voltage, inspect fuses,
wiring harness, connectors, and switches.
VOLTAGE (Brakelight)

NOTE: Perform this test on the main harness side of
the connector. Also, the ignition switch should be in
the ON position and the brake (either foot pedal or
hand lever) must be applied.
1. Set the meter selector to the DC Voltage position.
2. Connect the red tester lead to the red/blue wire; then
connect the black tester lead to the black wire.
3. With either brake applied, the meter must show
battery voltage.

NOTE: If the meter shows no voltage, inspect fuses,
wiring harness, connectors, and switches.

Ignition Timing

The ignition timing cannot be adjusted; however, verify-
ing ignition timing can aid in troubleshooting other com-
ponents. To verify ignition timing, use the following
procedure.
1. Attach the Timing Light to the spark plug high
tension lead; then remove the timing inspection
plug from the left-side crankcase cover.
2. Using the Tachometer, start the engine and run at
1500 RPM; ignition timing should be 10° BTDC.
3. Install the timing inspection plug.
