CHECKOUT PROCEDURE
Measure the resistance: Across two terminals with
an ohm-meter on highest scale.
HIGH-VOLTAGE
CAPACITOR
Including internal
bleeder
resistor
Measure the resistance: Across two terminals with
an ohm-meter on highest scale.
HIGH-VOLTAGE
DIODE
RESULT
Normal reading:
Momentarily indicates several ohms, and
gradually to 10 meg-ohms.
Abnormal reading:
Indicates continuity or 10 meg-ohms
from the beginning.
Figure 7
Normal reading:
Indicate about middle position in one
direction (forward) and infinite ohms in
the reverse direction, using ohm meter
with a 9V battery.
- 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
Figure 8
both directions.
