an ohm-meter on highest scale.
COMPONENT
HIGH-VOLTAGE
CAPACITOR
Including internal
bleeder
resistor
HIGH-VOLTAGE
DIODE
Measure the resistance: Across two terminals with
an ohm-meter on highest scale.
CHECKOUT PROCEDURE RESULT
Normal reading:
Momentarily indicates several ohms, and
gradually to 10 meg-ohms.
Abnormal reading:
Indicates continuity or 10 meg-ohms
from the beginning.
Normal reading:
Indicate about middle position in one
direction (forward) and infinite ohms in
the reverse direction, using ohm meter
with a 9V battery.
NOTE
- Some digital meter may show more
than 0 ohms or infinite ohms even in a
forward direction because the low mea-
suring voltage of the meter does not
allow the meter to pass through the high
voltage diode. Use an ohm meter with
a 9V battery.
Abnormal reading:
Indicates continuity or infinite ohms in
both directions.

Figure 9
Normal reading:
Indicate infinite ohms in both directions.
Abnormal reading:
Indicates continuity in both directions
or continuity in one direction and
infinite ohms in reversed direction.
