1. Using a suitable multimeter, 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.
2. 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
regulator is faulty or a battery connection is loose
or corroded. Clean and tighten battery connec-
tions or replace the alternator. If voltage does not
rise, check all battery connections, the battery (B+)
wire on the alternator, and the voltage regulator
control plug-in. If all are normal, replace the alter-
nator.
REMOVING
1. Remove the negative battery cable from the bat-
tery; then remove the seat and left-side engine
cover.
2. Disconnect the battery (B+) wire from the alterna-
tor; then disconnect the voltage regulator control
plug-in.

3. Loosen the alternator adjuster cap screw (A) and
the pivot bolt (B); then remove the alternator drive
belt.

4. Remove the adjuster cap screw and pivot bolt and
remove the alternator.
NOTE: The alternator/regulator is not a service-
able part; therefore, it must be replaced as an
assembly.
INSTALLING
1. Place the alternator/regulator into position on the
engine; then secure with the existing hardware. Do
not tighten at this time.
2. Place the alternator drive belt into position; then
using a suitable pry, tension the drive belt so that a
10 kg (22 lb) force applied at the midway point
will result in a deflection of 10-15 mm (0.4-0.6
in.).

3. Holding tension on the belt, tighten the adjuster
cap screw securely; then remove the pry and
tighten the pivot bolt securely.
4. Connect the battery (B+) wire and connect the reg-
ulator control plug-in; then connect the negative
battery cable to the battery.
5. Install the left-side engine cover and seat making
sure the seat latches securely.
