11-24. TESTING OF CHRYSLER ALT E R N ATOR POSITIVE RECTIFIERS USING C-3829
TESTER (Refer to Figure 11-20.)
a. Place rectifier end shield and stator assembly on an insulated surface.
b. Plug tester C-3829 power source lead into 110-volt ac power supply.
c. Connect test lead alligator clip of tester C-3829 to alternator output terminal.
d. Touch metal strap of each positive rectifier to test probe.
1. A reading of 1.75 amps or more is a satisfactory rectifier. Readings and direction of needle
movement must be the same for all three rectifiers.
2. When two rectifiers are good and one is shorted, reading taken at the good rectifiers will be
low and reading at shorted rectifier will be zero. Disconnect lead to rectifier reading zero and test. With the
defective rectifier disconnected, the reading of good rectifiers will be a satisfactory range.
3. When one rectifier is open, tester will read approximately one amp while the two good recti-
fiers will read within the satisfactory range.
11-25. TESTING OF CHRYSLER ALT E R N ATOR NEGATIVE RECTIFIERS USING C-3829
TESTER (Refer to Figure 11-21.)
a. Connect test lead alligator clip to rectifier end housing.
b. Touch metal strap of each negative rectifiers to test probe and note each reading.
c. Test indications for negative rectifiers are the same for positive rectifiers except test meter will
read on the opposite side of scale. (Refer to Note on next page.)
