TESTING OF NEGATIVE RECTIFIERS USING C-3829 TESTER. (Refer to Figure 24-6.)
1. Observe CAUTION noted in “Testing of Rectifier Assemblies.”
2. Connect test lead “alligator” clip to rectifier end housing.
3. Touch the metal strap of each of the negative rectifiers with the test probe and note the reading of each.
4. The test indications for the negative rectifiers are the same as for the positive rectifiers except the test
meter will read on the opposite side of the scale.
—NOTE—
If a negative rectifier shows shorted, isolate the stator from the
rectifier end shield and retest. It is possible that a stator winding
could be grounded to the stator laminations or rectifier end shield
which would indicate a shorted negative rectifier.
TESTING OF RECTIFIER ASSEMBLIES USING TEST LAMP.
1. Remove the nuts from the terminal block studs which secure the stator windings and the positive and
negative rectifier straps.
2. Lift off stator winding terminals and carefully pry the stator assembly from the end shield.
3. Test the rectifiers with a 12-volt battery and a test lamp equipped with a No. 67 bulb.
A. Connect one side of the test lamp to the positive battery post and the other side of the lamp to a
test probe.
B. Connect another test probe to the negative post of the battery.
4. Place one test probe on the rectifier heat sink and the other test probe on the strap on the top of the
rectifier. Note whether the test lamp lights or does not light. Repeat test for each rectifier.
5. Reverse the test probes (move probe from rectifier heatsink to rectifier strap and move probe from
rectifier strap to rectifier heatsink), and repeat the test for each rectifier.
—NOTES—
If the test lamp lights in one direction but not in the other, the
rectifier is satisfactory. However, if the test lamp “lights” in both
directions, the rectifier is “shorted.” If the test lamp fails to light
in either direction, the rectifier is open.
The lamp should light in the same direction for all rectifiers on
each assembly.
Replace rectifier and heatsink assemblies which have shorted or
open rectifiers.
