High voltage Transformer is
damaged
Measure the resistance
(Wire leads removed):
With an ohm-meter on R x1 scale.
a.
Primary winding;
b.
Secondary winding;
Normal readings:
a.
Approx. 2 ohm.
b.
Approx. 170 ohms.
7.12
Measure the resistance
(Wire leads removed):
(Ohm-meter scale: Rx10000)
a. Primary winding to
ground;
b. Filament winding to
ground;
Normal readings:
a.
Infinite ohms.
b.
Infinite ohms.
High Voltage capacitor damaged
Measure the resistance:
Terminal to terminal
(Wire leads removed)
(Ohm-meter scale: Rx1000)
Normal reading:
Momentarily indicates
several ohms, and then
gradually returns to infinite
ohms.
Abnormal reading:
Indicates continuity or
infinite ohms
from the beginning.
7.13
Measure the resistance:
Terminal to case
(Wire leads removed)
(Ohm-meter scale: Rx1000)
Normal readings:
Infinite.
Abnormal reading:
Indicates continuity.
High Voltage diode damaged
NOTE :
Some inexpensive meters
may indicate infinite
Normal readings:
continuity.
Abnormal reading:
Infinite.
