INSTALLATION SERVICE POINTS > >A<< THERMOSTAT INSTALLATION Install the thermostat so that the jiggle valve is facing straight up. Be careful not to
fold or scratch the rubber rin
g.
CAUTION: Make absolutely sure that no oil adheres to the
rubber ring of the thermostat. Also do not fold or
scratch the rubber ring during installation.

DESCRIPTION The charging system charges the battery with the generator output to keep the
battery charged at a constant level during varying electrical load. OPERATION Rotation of the excited field coil generates AC voltage in the stator. This alternating
current is rectified through diodes to DC voltage having a waveform. The average
output voltage fluctuates slightly with the generator load condition.
When the ignition switch is turned on, current flows in the field coil and initial
excitation of the field coil occurs. When the stator coil begins to generate power
after the engine is started, the field coil is excited by the output current of the stator
coil. The generator output voltage rises as the field current increases and it falls as
the field current decreases. When the battery positive voltage (generator S terminal
voltage) reaches a regulated voltage of approximately 14.4V, the field current is cut
off. When the battery positive voltage drops below the regulated voltage, the
voltage regulator regulates the output voltage to a constant level by controlling the
field current. In addition, when the field current is constant, the generator output
volta
ge rises as the en
gine s
peed increases. See Fig. 1
or Fig. 2

NOTE: See appropriate SELF DIAGNOSTICS article in ENGINE
PERFORMANCE to properly diagnose charging system.

ROTOR 1. Check the continuity between the slip rings of the field coil. If the resistance
value is not within 2-5ohm, replace the rotor. See Fig. 11
.
2. Check the continuity between the slip ring and the core. If there is continuity,
re
place the rotor. See Fig. 12
.

RECTIFIER 1. Check the continuity between the positive rectifier and the stator coil lead
connection terminal with a tester. If there is continuity between the terminals,
the diode is shorted, so replace the rectifier. See Fig. 13
.
2. Check the continuity between the negative rectifier and the stator coil lead
connection terminal with a tester. If there is continuity between the terminals,
the diode is grounded, so replace the rectifier. See Fig. 14 .
3. Check the continuity of the 3 diodes by connecting an ohmmeter to both ends
of each diode. If there is continuity between the directions, or if there is no
continuit
y, the diode is dama
ged, so re
place the rectifier. See Fi
g. 15
.
