Start the engine, and note the voltage readings at various
engine speeds. The readings should show nearly battery
voltage when the engine speeds is low, and, as the engine
speed rises, the readings should also rise. But they must
be kept under the specified voltage.
Stop the engine and disconnect the digital meter.
If the charging voltage is kept between the values given in
the table, the charging system is considered to be working
If the charging voltage is much higher than the values
specified in the table, the regulator/rectifier is defective
or the regulator/rectifier leads are loose or open.
If the charging voltage does not rise as the engine speed
increases, the regulator/rectifier is defective or the alter-
nator output is insufficient for the loads. Check the al-
ternator and regulator/rectifier to determine which part is
