megger.

(6) Rectifier
The circuit diagram of the rectifier is shown in Figure
T190. Use the K
Ω
range of the circuit tester and check
for continuity.
The rectifier is good if continuity is measured in one
direction through the diode but not in the other.
NOTE: The condition of the rectifier cannot be
determined by measurement of resistacne
in the right direction. Diode characteristics
bring forth a great difference in current in
the right direction, according to the source
voltage and, therefore, measurement is
different depending on the type of tester
and its range of resistace.
This is the reason why the rectifier is
judged good when the difference in
resistances measured in the right and in the
reverse directions is big.
Do not use a 500 V megger for measuring
because it will destroy the rectifier.
(7) Brush
Measure length of brush protruding from the brush
holder.
Example: Standard
10.5
mm
Limit of use
4.5 mm
