Alternator System
(Refer to Figure 2) The alternator serves as the main compo-
nent to power the electrical system and charge the battery
during normal conditions.
The alternator system consists of the alternator, the alterna-
tor relay (2, Figure 1), an optional 60 A fuse (1, Sheet 1), the
alternator switch and the associated wiring.The alternator
features an integrated DC converter and voltage regulator.
The voltage regulator is adjusted to 14 Volts. The alternator
is mounted at the right front of the engine.
Up to SN LT004 and for SN LT009 and LT010 the alternator
relay (2, Figure 1, Sheet 1) and the fuse (1) are located at the
lower left cockpit side of the firewall.
From SN LT005 (except SN LT009 and LT010) the alternator
relay (2, Figure 1, Sheet 2) is part of the electrical main
board. The optional fuse is now obsolete.
The ALTERNATOR switch (all SN) is located on the left side
of the rear instrument panel. The toggle type ALTERNATOR
switch features a red cap.
Placing the ALTERNATOR switch to the ON-position will
energize the alternator solenoid which provides a circuit
from the bus bar to the alternator. The voltage regulator will
supply and control the exitation current to keep the output
voltage of the alternator constant under varying output cur-
rent requirements.
With the alternator power available, the battery will be
charged from the bus bar. The ammeter, which is in series
with the battery and the bus bar will indicate the current flow
(positive value) to the battery. When the battery reaches a
state of full charge, the ammeter will show an indication near
"0".
