To load
The charging system consists of an A—C generator, silicon diode rectifier, voltage regulator and storage battery. The A—C
generator has a rotor which is directly driven by the engine crankshaft.
Silicon rectifier is used to convert the A—C current into D—C current to charge the battery. The voltage regulator limits the
output voltage.
Charging test
1. Use a fully charged battery for the test. (The specific
gravity
of
the
electrolyte
in
each
cell
must
be
1.260—1.280 at 20°C or 68°F)
2. Connect the negative probe of an ammeter to the positive
terminal of the battery, and the positive probe to the
harness.
3. Connect the probes of a voltmeter to the battery terminals
in similar polarity.
4, Run
the engine under the condition of NIGHT
AND
DAYTIME RIDING, and take the meter readings.
If the readings are out of the charging characteristics as
specifed on next page, check the generator, battery and
rectifier for condition.
