Charging System Operational Inspection
•
Check the battery condition.
NOTE
○
Always check the battery condition before judging other
parts of the charging system. The battery must be fully
charged for accurate charging system tests.
•
Warm up the engine to bring the components up to their
normal operating temperatures.
•
Measure regulated output voltage at various engine
speeds.
○
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 is defective, or the regulator leads are loose
or open.
If the output voltage does not rise as the engine speed
increase, the regulator is defective or the alternator output
is insufficient for the loads.
