Charging System Inspection; Regulated Voltage Inspection - Honda 1998 VT750C Service Manual

)
CHARGING SYSTEM INSPECTION
NOTE:
• Measuring circuits with a large capacity that
exceeds the capacity of the tester may cause
damage to the tester. Before starting each test,
set the tester at the high capacity range first, then
gradually down to low capacity ranges in order
to ensure that you have the correct range and do
not damage the tester.
• When measuring small capacity circuits, keep the
ignition switch off. Ifthe switch is suddenly turned
on during a test, the tester fuse may blow.
REGULATED VOLTAGE INSPECTION
!!!!!IIIl- _
• If the engine must be running
to
do some work,
make sure the area is well-ventilated. Never run
the engine in an enclosed area.
• The exhaust contains poisonous carbon
monoxide gas that may cause loss of
consciousness and may lead
to
death.
Remove the battery (page 16-5) and install the fully
charged battery.
Start the engine and warm it up to the operating
temperature; stop the engine.
Connect the multimeter between the positive and
negative terminals of the battery.
CAUTION:
• To prevent short, make absolutely certain which
are the positive and negative terminals or cable.
• Do not disconnect the battery or any cable in the
charging system without first switching off the
ignition switch. Failure to follow this precaution
can damage the tester or electrical components.
With the headlight to Lo beam, restart the engine.
Measure the voltage on the multimeter when the
engine runs at 5,000 rpm.
REGULATED VOLTAGE: 14 -15 V/4,OOO rpm
The battery is normal if the voltage reads the
regulated voltage on the tester.
NOTE:
The speed at which voltage starts to rise cannot be
checked as it varies with the temperature and loads
of the generator.
