D.C. GENERATION (cont.)
(1) Description (cont.)
(e) The brush and holder assembly is installed in a cavity inside the rear housing. The brushes
ride the surfaces of the slip rings on the rotor shaft under spring pressure and transmit field
current through their circuit to ground. One brush or field terminal is, therefore, insulated
from the housing.
(f) The rectifier assembly is located between the stator and the inside surface of the rear hous-
ing. Attachment to the housing is made by means of mounting studs that protrude from the
positive and negative diode plates (heat sinks). The positive plate is insulated from the hous-
ing, and the negative plate is grounded to the housing through the studs. The rectifier assem-
bly has a printed circuit board spaced away from the heat sinks. (Refer to Figure 19.)
The stator winding leads are soldered to integral terminals on the back of the circuit board.
The stator phase top is attached to the insulated stator terminal. The heat sinks are attached to
the circuit board with insulated spacers and roll pins maintaining the necessary separation
between the two assemblies. The diodes themselves are exposed. The rectifier assembly has
three diode plates connected to an AC potential. Each of the three plates is connected to one
of the three stator leads. Two steel conductor plates or “bus bars”, one positive and the other
negative, circle the diodes beginning at the “BAT” and “GND” terminal studs. The bus bars
act as termination points for collecting the DC current from the terminal wire of each diode.
One positive and one negative diode is soldered to each of three stamped aluminum plates to
form the plate and diode assemblies. The aluminum plates serve as heat sinks to cool the
diodes by providing increased surface area to the air flow through vent slots in the rear hous-
ing to the fan at the front of the alternator.
One plate and diode assembly is connected to each of the three leads to form the full wave
bridge rectifier. Diode terminal wires are connected to the bus bars by means of a flexible
connector wire. One diode is connected to the positive bus bar, and the other diode, on each
plate, is connected to the grounded or negative bus bar. (Refer to Figure 20.)
(2) Precautions
As a preface to testing the charging system, it cannot be over-emphasized how important it is to
observe the precautions listed. Considerable time and expense can be saved by following these
simple rules.
(a) Always disconnect the battery ground cable before disconnecting wiring or components of
system.
(b) Avoid contacting alternator output terminal (BAT) as it is directly connected to the battery
bus voltage anytime battery cables are connected and “BAT” portion of master switch is ON.
(c) Never connect the battery ground cable until all system wiring connections and components
are complete.
(d) When adjusting belt tension, always apply force near pulley of the alternator to avoid damage
to stator and rectifier, or use a 1 1/8” O.E. Wrench on the adjustment lug of the alternator case
casting.
(e) Never attempt to polarize the alternator. Polarizing is not applicable to alternator and could
damage the regulator.
(f) Observe polarity when installing a battery in aircraft. Reverse polarity will destroy the diodes
in alternator.
(g) Always connect a booster battery in parallel, negative to negative, positive to positive.
