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 reg-
ulator 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.
Starter Motor
NOTE: The starter motor is not a serviceable com-
ponent. If the starter is defective, it must be replaced.
REMOVING
1. Disconnect the battery.
2. Remove the nut securing the positive cable to the
starter; then remove the cable from the starter.
3. Remove the two cap screws securing the starter with
ground wires to the crankcase; then remove the
starter. Account for the wiring forms and an O-ring.
INSTALLING
1. Apply a small amount of grease to the O-ring seal on
the starter; then install the starter into the crankcase.
Secure with two machine screws and wiring forms.
2. Secure the positive cable to the starter with the nut.
3. Connect the battery.
TESTING VOLTAGE
Perform this test on the starter positive terminal. To
access the terminal, slide the boot away.
NOTE: The ignition switch must be in the ON posi-
tion, and the shift lever in the NEUTRAL position.
1. Set the meter selector to the DC Voltage position.
2. Connect the red tester lead to the starter terminal;
then connect the black tester lead to ground.
3. With the key switch momentarily held in the start
position, the meter must show battery voltage and the
starter should operate.
HDX282
NOTE: If the meter showed correct voltage but the
starter motor did not operate or operated slowly,
troubleshoot all starting system components before
replacing the starter motor.
NOTE: If the meter showed no battery voltage,
inspect the main fuse, ground connections, starter
lead, battery voltage (at the battery), starter relay, or
the neutral start relay.
Starter Relay
1. Remove the seat, seat back, and seat base; 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 ter-
minal; then connect the black tester lead to the starter
cable connection on the starter relay. The meter must
show battery voltage.
HDX281A
NOTE: Make sure the ignition switch is in the ON
position and the transmission in neutral.
3. Rotate the key switch to the starter position while
observing the multimeter. 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 con-
tinues 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.
CAUTION
Do not run the engine at high RPM for more than 10 sec-
onds.
CAUTION
Always disconnect the negative battery cable from the
battery first; then disconnect the positive cable.
