Suzuki GS500E (1989-1997) [178/221] No load
(positive (+ve) lead to battery positive (+ve)
terminal, negative (-ve) lead to battery
negative (-ve) terminal). Slowly increase the
engine speed to 5000 rpm and note the
reading obtained. At this speed the voltage
should be 13.5 to 15.5 volts. Stop the engine
and turn off the lights. If the voltage is outside
these limits. perform a no-load output check
as described in the foliowing Step, and also
check the regulator/rectiflW (see SectIon 35).
Note: If the voltage Is below 13.5 volts. then It
is more Hkeiy that the altemator is faulty. "the
voltage ;s above 15.5 volts. It ;s more likely
that the regulator Is faulty.
Output test - no-load
A Warning: If in any doubt about
, your ability to cany out this test,
. entnlst It to a Suzuki dealer.
8 Remove the left-hand side panel (see
Chapter 7). Trace the alternator wiring back
from the top of the engine sprocket cover and
disconnect It at the connector. Start the
engine and Increase the engine speed to
33.3 The cover I. secured by ten bolts (arrows)
Electrical system 8-21
2 Unscrew the gearchange lever pinch bolt
and remove the lever from the shaft. noting any
alignm81t ~ on the lever ~ the shaft. "
no marks are visible. make your own before
removing the lever so that it can be correctly
aligned with the shaft on installation. Unscrew
the bolts securing the qine sprocket COV8' to
the crankcase and move the cover aside. There
is no need to detach the ckJtch cable from the
cover. Release the alternatOf' wiring from the
clamp next to the neutral switch.
3 Working In a criss-cross pattern. evenly
slacken the left-hand side crankcase cover
retaining bolts (see Illustration). Uft the cover
away from the engine. being prepared to
catch any residual 011 which may be reIea88d
as the cover is removed. Remove the gasket
and discard it. Note the position of the
locating dowel fitted to the crankcase and
remove it for safe-keeping If it is loose. Note
that the starter idle/reduction gear shaft
locates into the crankcase covw and .:ta as a
second locating dowel. Note: "only the stator
coils require attention, refer to Step 7.
4 To remove the rotOf' bolt It Is nece8.-y to
stop the rotOf' from rotating. " a rotOf' holding
strap or tool is not available, place the
transmission in gear and have an assistant
apply the rear brake. or alternatively use a
suitable spanner on the flats of the middle
section of the rotor. Unscrew the bolt (see
IIhJstr8tion).
5000 rpm by adjusting the throttle stop screw
underneath the carburettors.
Caution: Do not run the engine at this
speed for any longer than Is nece8U'Y to
take this reading, otherwise It willovemeat
and engine damage may result.
9 Using a multimeter set to the 0 - 100 volts
ac scale (voltmeter), measure the voltage
between each of the wires on the alternator
side of the connector, so that three separate
readings are taken in all (..e illustration).
Compare the readings taken to the minimum
no-load voltage specified at the beginning of
the Chapter. If any of the readings are below
the minimum specified, check the statOl' coil
resistance (see Section 34).
10 On completion of the test, re-set the
engine idle speed (see Chapter 1). Stop the
engine and recomect the altematOl' wiri1g.

1 Remove the left-hand side panel (Chapter 7).
Trace the a/t~tor wirW1g beck from the top of
the engine sprocket cover and disconnect it at
the connectors (see illustration). Release the
wiring from any clips or ties.
