Charging System Operational Inspection
•
Check battery condition.
NOTE
○
Always check battery condition before condemning
other parts of the c harging system. The battery must
be fully charged in order to conduct accurate charging
system tests.
•
Warm up the engine to bring the components up to their
normal operating temperatures.
•
Measure regulator/rectifier output voltage at various en-
gine speeds with the headlights turned on and then turned
off.
○
Connect a voltmeter across the battery terminals.
•
The readings should show nearly battery voltage when
the engine speed is low, and as the engine speed rises,
the readings should also rise. But they must stay within
the specified range.
If the output voltage is much higher than the specification,
the regulator/rectifier is defective, or the regulator/rectifier
wires are loose or open.
If the output voltage does not rise as the engine speed
increase then the regulator/rectifier is defective or the al-
ternator output is insufficient for the loads.
Regulator/Rectifier Output Voltage
Standard:
Battery Voltage ∼ 15 V
