Charging System Operational Inspection
•
Check battery condition.
NOTE

Always check battery condition before condemning other parts of
the charging 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 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 dose not rise as the engine speed increase, the
regulator is defective or the alternator output is insufficient for the
loads.
Regulated Output Voltage
Battery Voltage to 15 VDC/3600 rpm
