DSG-423 CHARGING SYSTEM
06-3
GENERAL INFORMATION
Description
WARNING: REFER TO CAUTIONS & WARNINGS AT
THE BEGINNING OF THIS SECTION.
The charging system consists of a generator, voltage
regulator and battery. A serpentine belt drives the
generator from the crankshaft pulley -- refer to Section
5 for information on the drive belt.
The generator produces alternating current which is
subsequently converted to direct current
The charging rate is adjusted automatically by the built-
in regulator to provide sufficient electric current to keep
the battery fully charged under normal operating
conditions.
Battery power
The battery is a 12 volt DC source connected in a
negative ground system. There are three main functions
of the battery:
• To supply power to the starter and ignition system so
the engine can be cranked and started.
• To supply extra power required when the equipment
load requirements exceed the supply from the
charging system.
• To act as a voltage stabilizer by smoothing out or
reducing temporary high voltages within the
electrical system.
Operation
With the ignition on, voltage is applied to the voltage
regulator. This turns the regulator on, allowing current to
flow from the battery to the generator field coil.
When the engine is started, the generator begins to
generate alternating current (AC) which is internally
converted to direct current (DC). This current is then
supplied to the equipment electrical system through the
B+ terminal of the generator.
Once the generator begins generating current, a
voltage signal is taken from the generator stator and fed
back to the regulator. This voltage feedback signal
(typically half the battery voltage) is used to turn off the
warning indicator.
With the system functioning normally, the generator
output current is determined and compared to a set
voltage internal to the regulator, and the regulator
controls the generator field current to maintain the
correct generator output.
The set voltage varies with temperature and typically is
higher in cold temperatures and lower in warm
temperatures. This allows for better battery recharge in
the winter and reduces the chance of overcharging in
the summer.
