Starter Relay; Engine Control Module (Ecm); Regulator/Rectifier; Testing Regulator/Rectifier - Arctic Cat WILDCAT/X Service Manual

3. With the starter button depressed, the meter must
show battery voltage and the starter motor should
operate.
 NOTE: If the meter showed battery voltage but the
starter motor did not operate or operated slowly,
inspect battery voltage (at the battery), starter motor
condition, and/or ground connections.
 NOTE: If the meter showed no battery voltage,
inspect the main fuse, ground connections, starter
motor lead, battery voltage (at the battery), starter
relay, or the neutral start relay.

Starter Relay

1. Remove the battery cover; then using the multimeter
set to the DC Voltage position, check the relay as fol-
lows.
2. Connect the red tester lead to the positive battery
cable; then connect the black tester lead to the starter
cable connection on the starter relay. The meter must
show battery voltage.
Red Tester Lead
 NOTE: Make sure the ignition switch is in the ON posi-
tion and the transmission is in park.
3. Depress the starter button while observing the multi-
meter. The multimeter should drop to 0 volts and the
stater should engage.

 NOTE: If the starter engages and more than one volt
is indicated by the multimeter, replace the starter
relay. If no "click" is heard and the multimeter contin-
ues to indicate battery voltage, proceed to step 4.
4. Disconnect the two-wire plug from the starter relay;
then connect the red tester lead to the green wire and
the black tester lead to the black wire.
5. Depress the starter button and observe the multimeter.
 NOTE: If battery voltage is indicated, replace the
starter relay. If no voltage is indicated, proceed to
Power Distribution Module (PDM) check.
Engine Control Module
(ECM)
The ECM is located beneath the passenger seat.
 NOTE: The ECM is not a serviceable component. If
the unit is defective, it must be replaced.
The ECM is rarely the cause of electrical problems; how-
ever, if the ECM is suspected, substitute another model-
compatible ECM to verify the suspected one is defective.
This EFI system has a built-in feature that will only allow
an ECM of the same part number to be used in these mod-
els. Do not attempt to substitute an ECM from a different
model as the system will not allow it to start.
Error codes can be cleared by following the procedures
located in the EFI Diagnostic System sub-section in this
section.

Regulator/Rectifier

The regulator/rectifier is located under the hood above the
differential. Verify all other charging system components
before the regulator/rectifier is replaced.
TESTING
1. Start engine and warm up to normal operating temper-
ature; then connect a multimeter (set at the DC Volt-
age position) to the battery as follows.
