Rectifier
NOTE:
•
Be sure to confirm the specification of the ohmmeter to
be used for inspection before putting it into use.
•
The current flow direction differs according to the de-
sign of an ohmmeter.
•
This manual is described, based on a digital tester
manufactured by DENSO Japan.
<Reference>
•
The measured resistance should be about the same as
those of other rectifiers, for the measurement results
differ according to the input voltage of each tester.
•
If the measured resistance of the rectifier differs more
than 20 percent, replace the rectifier holder.
1. Inspection of rectifier at positive side
(1) Ensure that continuity exists between the positive stud
bolt of the rectifier holder and the rectifier terminal by
connecting an ohmmeter as indicated in the right fig-
ure.
If no continuity exists, replace the rectifier holder.
(2) Ensure that no continuity exists between the positive
stud bolt of the rectifier holder and the rectifier terminal
by connecting an ohmmeter as indicated in the right
figure.
If continuity exists, replace the rectifier holder.
2. Inspection of rectifier at negative side
(1) Ensure that continuity exists between each of the neg-
ative terminals of the rectifier holder and each rectifier
terminal by connecting an ohmmeter as indicated in
the right figure.
If no continuity exists, replace the rectifier holder.
(2) Ensure that no continuity exists between each of the
negative terminals of the rectifier holder and each rec-
tifier terminal by connecting an ohmmeter as indicated
in the right figure.
If continuity exists, replace the rectifier holder.
