The
retaining
tab
raust
be
pulled
out of
the slot before
the faulty ooil ean be
removed from the stator
post.
When
installing
new
c,oil,
position
tab with elip
in hole
on stator, then slip coil over
tab and stator
post.
After
the coil
is
in
place,
bend
protruding
end of tab
over to
prevent
interference
with
magnet ring.
No
adjustments are
possible
on
the alternator
system and fteld service
on
this
system
is not recommended.
The
faulty
part
should
be replaced by a new
part.
&epair of the
rectiffer-regulator, which
is a sealed
unit, le-
quires
the
use
of special test equipment available only at the
place
of manufacture.
Stator
repairs must also be
performed with special equipment.
The
accompanying Trouble
Analysis Chart can be
used
to
pinpoint
the
faulty
part.

TEST B
-With
Bf cable
reconnected, check Bf
(at
terminal on recti$er-regulator) to
ground
with
DC Voltmeter.
If
13.8
volts
or higher,
place
load
(lights)
on
battery
to reduce voltage
below 13.6
volts:
B-t
*
If charge rate increases.
B-Z-If charge
rate does not increase.
