TESTING RECTIFIERS
(NEGATIVE).
To test the
negative case rectifiers
in the end shield, connect the alligator clip of tool C-3829 to the end shield.
Touch the test prod to the bare wire of the rectifier leads at the rectifiers
in the end shield. The meter will indicate the condition of the rectifier.
The test indications are the same for the negative case rectifiers in the
end shield as they are for the positive case rectifiers in the heat sink. However,
the meter will read
at the opposite end of
the scale.
NOTE
If all three
of the negative rectifiers
read low, before
condemning the
rectifiers, test for a grounded
stator.
A grounded stator will cause the negative rectifiers
(in the end shield) to read low.
NOTE
A common
cause of
an open or
a shorted
rectifier is
a defective capacitor or a battery that has been installed
