IMPORTANT
The battery must always be connected, when the
alternator is running.
Do $1 mix up the battery connections, confusion
leads to serious damage to the alternator.
The alternator requires very little maintenance, be-
cause carbon brushes and commutators are not
needed for the output current.
The alternator has two slip rings respectively two
carbon brushes to transmit exciting current to the
alternator field windings on the rotor.
The load on these brushes and slip rings is, however,
that light that normally they do not require super-
vision.
Maintenance with regular intervals is therefore not
prescribed for this alternator. Repair of the A.C.
generator should be carried out by a specialized
service garage, as it is vital that disassembly and
testing are carried out correctly. Even minor mis-
takes may cause great damage.
NOTE
For exitation of the alternator, use the charge indi-
cator light. This must be of 1.2—2.0 W.
WARNING
When
electrowelding on a car equipped with an al-
ternator, the battery ground- and all connections on
the alternator shall be disconnected before. Other-
wise damage will be caused to the rectifier diodes.
As from chassis No. 95753002472 and 96752013172 an
alternative alternator is used. It is identic with the one
used in Saab 99 up to and incl. model 1974, but minor
modifications are made.
The slip ring bearing bracket is turned half turn to suit
the installation bracket. The fan disc is exchanged against
the Saab 95/96 disc. A new alternator stay is introduced
which is interchangeable with earlier design. The alter-
nator which is not stocked as spare part is marked with
Bosch No. 0 120 400 850. Concerning integral parts, see
spare parts catalogue, Saab 99.
