Charging Output Check (Dr350S) - Suzuki DR350 Service Manual

OR3505 8-28
When the engine speed increases and the load decreases. the battery charge voltage will increase
due to the generated voltage by the generator. The battery
will
continue to
be
charged by the gener-
ated voltage until the battery voltage (voltage between @ and @ ) reaches the value set of the control
circuit in the regulator, then a signal from the circuit will flow to the SeR. When the SeR goes " ON ".
O and @will
become conductive , hence the voltage does
not
cha rge the battery but
returns to
the
generator.
When the battery voltage falls . the signal to the
seA
will be
out otf , causing the
SeR
to go " OFF" .
As a result, the generated voltage will start to charge the battery once again . Due to the repetition
of the above operation of the regulator. the battery voltage will be maintained constant, preventing
o vercharging of the battery_

INSPECTION
CHARGING OUTPUT CHECK
• Remove the left frame cover _
• Start the engine and keep it running at 5 000 rl min with
the lighting swtich turned ON (High position).
• Using the pocket tester , measure the DC voltage between
the battery
®
terminal and
e
terminal. If the tester reads
under 13.0V or over 15. 5V, check the AC generator no-
load performance and regulator/rectifier .
NOTE:
When making this test, be sure that the battery is in fully-
charged condition.
STD charging output:
13.0 -15.5V
(DC) at 5 000 r/min
