27.9 Continuity should exist between the
or emery paper. After cleaning, wipe away any
residue with a cloth soaked in electrical
system cleaner or denatured alcohol.
9 Using an multimeter or test light and
battery, check for continuity between the
commutator bars (see illustration). Continuity
(zero resistance) should exist between each
bar and all of the others.
10 Also, check for continuity between the
commutator bars and the armature shaft (see
illustration). There should be no continuity
(infinite resistance) between the commutator
and the shaft. If the checks indicate
otherwise, the armature is defective.
11 Check the front end of the armature shaft
for worn or chipped teeth and check the
condition of the armature bearing (see
illustration 27.8).
12 Reassemble the starter motor in the
reverse order of disassembly.
13 Hold the brushes back against the
pressure of their springs and fit the armature
into the end cover carefully to avoid damaging
the seal. Check that each brush is securely
pressed against the commutator by its spring
and is free to move easily in its holder.
14 Lubricate the bush in the end of the
housing with a smear of grease, then fit the
seal and housing over the armature. Tighten
the housing screws securely.

1 If the performance of the charging system
is suspect, the system as a whole should be
checked first, followed by testing of the
individual
components.
Note:
Before
beginning the checks, make sure the battery is
fully charged and that all system connections
are clean and tight.
2 Checking the output of the charging system
and the
performance of the various
components within the charging system
requires the use of a multimeter (with voltage,
commutator bars
27.10 There should be no continuity between the commutator
bars and the armature shaft
current and resistance checking facilities).
3 When making the checks, follow the
procedures carefully to prevent incorrect
connections or short circuits, as irreparable
damage to electrical system components may
result if short circuits occur.
4 If a multimeter is not available, the job of
checking the charging system should be left
to a Peugeot dealer.

1 If the charging system of the machine is
thought to be faulty, perform the following
checks.
Leakage test
2 Disconnect the battery negative (-ve)
terminal.
3 Set the multimeter to the Amps function
and connect its negative (-ve) probe to the
battery negative (-ve) terminal, and positive
(+ve) probe to the disconnected negative (-ve)
lead (see illustration). Always set the meter
to a high Amps range initially and then bring it
down to the mA (milli Amps) range; if there is a
high current flow in the circuit it may blow the
meter's fuse.
Caution: Always connect an ammeter in
series, never in parallel with the battery,
otherwise
it
will be damaged. Do not turn
the ignition ON o r operate the starter
motor when the ammeter is connected
-
a
sudden surge in current will blow the
meter's fuse.
4 While Peugeot do not specify an amount, if
the current leakage indicated exceeds 1 mA,
there is probably a short circuit in the wiring.
Disconnect the meter and connect the
negative (-ve) lead to the battery, tightening it
securely,
5 If leakage is indicated, use the wiring
diagrams at the end of this book to
systematically disconnect individual electrical
components and repeat the test until the
source is identified.
Output test
6 Remove the belly panel (see Chapter 7).
Start the engine and warm it up to normal
operating temperature, then stop the engine
and turn the ignition OFF.
7 To check the unregulated voltage output,
connect a multimeter set to the

AC scale (voltmeter) between the yellow wire
terminal in the alternator wiring connector (see
Section 31) and the battery negative terminal.
8 Start the engine and allow it to idle, then
slowly increase the engine speed and note the
reading obtained. The unregulated voltage
should be as specified at the beginning of this
Chapter. If the voltage is not within these
limits, have the alternator checked by a
Peugeot dealer.
