NOTE: Make sure the ignition switch is in the ON
position, 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.

5. Depress the starter button and observe the multimeter.
NOTE: If battery voltage is indicated, replace the
starter relay.
Electronic Control Module
(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; how-
ever, if the ECM is suspected, substitute another ECM to ver-
ify 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 this
model. 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 EFI Diagnostic System sub-section in this
section.
Regulator/Rectifier
NOTE: Preliminary checks may be performed on this
component using the diagnostic mode on the LCD
gauge (see EFI Diagnostic System in this section).
The regulator/rectifier is located under the seat next to the
battery. Try to verify all other charging system components
before the regulator/rectifier is replaced.
TESTING VOLTAGE
1. Start engine and warm up to normal operating tempera-
tures; 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.
3. 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 regu-
lator is faulty or a battery connection is loose or cor-
roded. Clean and tighten battery connections or
replace the regulator/rectifier. If voltage does not rise,
replace the regulator/rectifier.
Headlights
The connectors are the four 2-prong ones secured to the
headlight bulbs (two on each side).
VOLTAGE
NOTE: The low beams are the outside bulbs (black
and white wires) and the high beams are the inside
bulbs (yellow and black wires). Always connect the
black tester lead to the black wires. The ignition
switch must be in the ON position.
1. Set the meter selector to the DC Voltage position.
2. Set the light switch to the correct position for the
affected light; then connect the black tester lead to the
black wire using a MaxiClip.
3. Connect the red tester lead to the yellow wire (high
beam) or white wire (low beam) using a MaxiClip. The
meter must show battery voltage.
NOTE: If battery voltage is not shown in any test,
inspect the LIGHTS fuse on the power distribution
module, headlight switch, ignition switch, switch
connectors, or wiring harness.
