Excitotion of the olternotor by o current
supply outside the cor is not permitted.
Agoin the semiconductors would suffer.
h) A blown chorging worning lomp must be
reploced immediotely with o new
one. Other-
wise correct excitotion of the olternotor is
not ensured. Use o new lomp of
the some
roting (or input), i.
e., 1.5
to 2 W.
i) Be sure thot there is
o perfect
electricol
connection on the connecting terminols ond
thot the olternotor
ond regulotor
ore properly
eorthed.
i) The
olternotor is oeroted, open. Therefore
toke core when woshing the cor thot woter
or cleoning ogents do not get
into it through
the venting holes.
Removing the Alternqtor
1. Disconnect the bottery.
2. Disconnect the olternotor leods. lt will be
helpful to remember the colour of one conductor
ond its connection for reinstollotion.
3. Remove oll ports
holding the olternotor on
the engine, ond lift owoy the olternotor.
Reinstolling the Alternotor
1. Cleon oll mounting surfoces.
For the olter-
notor mounting, see Chopter 2.3, por.42.
2. With the bottery
disconnected, insert the
conductors into the respective
connectors "M,,
ond "R"
(the conductors beor the some sym-
bols), ond fosten the remoining leod with o nut.
3. Reconnect the botterv. Alternotor

2. Lift the brushes with o hook proceeding
through the holes in the

This disossembly will give
occess to the

iobs,
with the exception of the renewol of the beor-
ing, should be done by experts in speciolized
repcir shops -
see the note supplementing the
following porogrophs.
Alternotor Reossembly
1. Insert the circlip into the becring bore
in
the commutotor end shield.
2. Fit the drive end shield with beoring on
the rotor shoft.
3. Assemble the stotor with the rotor ond the
commutotor end shield. 4" Tighten the olternoior with clomping bolts
ond check the rotor for free rototion while
tightening the bolts.
5. Slip the spocer on to tlre shoft,
top the

fit the fon ond belt pulley,
ond
tighten the entire ossembly using the nut with

brushes
in their lifted position.
Replocement of Beorings

1. Pull the beoring off the rotor
using o suit-
oble puller.
When ref itting the beoring, press

mondrel (drift).
On reossembly,

Checking Voltoge Regulotor
on Cor
The regulotor operotion con be offected by
loosened connections ond on imperfect eorth- ing.
lf the wsrning lomp does not go
o.ut when
driving, i. e., if it glows
ot increosed engine
speed brightly or dimly,
or if it does not stort
glowing ofter stopping
the engine ond
o new
iurning of the ignition key in
the switch box,
the voitoge regulotor
is probobly
foulty. Another
symptom of o regulotor
foilure is
o poor
chorg-
irrg of tlre bottery or its
overchorging.. lf there
is nothing wrong with the regulotor, check the
reguloted voltoge over the regulotor which
slrould reod 13.2 volts ot the
minimum ond 14.8
volts ot the moximunr. This check
in the

Electricol Adiustment
The voltoge regulotot- should be tested
ond
odjusted only on o test bench
in o connection
slrown in Fig. 13.412.
At o lood of some
2

voltoge should correspond to
volues specified
in the column "Checking".
lf the checked volt-
oge is within the specified ronge, do
not odiust
the regulotor. Othenwise odiust it to the volues
specified in the column "Adiustment".
lf woter
evoporotes obnormolly from the bottery, odiust
the voltoge regulotor to the bosic volues of

not
exceed 65 omperes (not
considering the peok

the first momentous deflection).
The storter motor must run noiselessly,
smoothly, ond the pinion
must move smoothly

must not ro-
tote direct on the foce of the slip-on ring. The

The position
of the door cotch retoiner on
the door pillor
ond/or the reor wing foce con
be odiusted within certoin limits ofter loosen-
ing its fostening screws. Adiust the retoiner
in the required position,
check the door for cor-
rect closing ond fitting
with the other ports
of

the screws.
The door cotch must slide
on to the leodlng
surfoce of the retoiner
so thot it rests
ogoinst

o pocking piece
under the retoiner (to
prevent
the fouling of the door cotch pin).
ln such
o cose, mork the position
of the
cotch on the
bodywork, slocken the screws, ond instoll o
pocking piece under the retoiner slipping it
over the lower screws ond
tipping it into po-
sition on the upper screws. It is importont to observe the correct ongle
of the inclinotion of the retoiner leoding sur-
foce, which hos to
correspond with the incli.
notion of the beoring surfoce of the door cotch
(outer door lock). Therefore, fosten the bose
plote of the retoiner so thot its upright stiffener
is porollel
with the edge of the moulded recess
for the retoiner
on the door pillor
ond the reor
wing. The leoding surfoce of the retoiner is provided
with o friction plote.
In the cose of domoge
(excessive weor, impoct of on incorrectly od-
iusted door, etc.),
prise
off the originol friction
plote ond fit o new one. lf the friction plote is
locking or if it is excessively worn, the door is
opt to rottle.
