
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 seats and center console; then using the
multimeter set to the DC Voltage position, check the
relay as follows.
2. Connect the red tester lead to the positive battery
cable connection; then connect the black tester lead
to the starter cable connection. The meter must show
battery voltage.


NOTE: Make sure the ignition switch is in the ON posi-
tion, transmission in neutral, and parking brake set.
3. Depress the starter button while observing the multi-
meter. The multimeter should drop to 0 volts and a
“click” should be heard from the relay.

NOTE: If a “click” is heard and more than one volt is
indicated by the multimeter, replace the starter relay.
If no “click” is heard and the multimeter continues 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.
PR841B
5. Depress the starter button and observe the multime-
ter.

NOTE: If battery voltage is indicated, replace the
starter relay. If no voltage is indicated, proceed to
Neutral Start Relay check.
Electronic Control Unit
(ECM)
The ECM is located beneath the seat near the battery.

NOTE: The ECM is not a serviceable component. If
the unit is defective, it must be replaced.
The ECM is rarely the cause for electrical problems;
however, if the ECM is suspected, substitute another
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
models. Do not attempt to substitute an ECM from a dif-
ferent model as the system will not allow it to start.
Error codes can be cleared by following the procedures
located in the ECM Error Codes sub-section in this sec-
tion.
Regulator/Rectifier
The regulator/rectifier is located under the operator’s seat
next to the battery. Try to verify all other charging system
components before the regulator/rectifier is replaced.
TESTING
1. Start engine and warm up to normal operating tem-
perature; then connect a multimeter (set at the DC
Voltage position) to the battery as follows.
2. Connect the red tester lead to the positive battery
post and the black tester lead to the negative battery
post.
