, windings

,

Fuses blown. Low resistance

shorting to frame or screen

between windings and earth.

One diode in bridge open

Circuit behaves as a half-

circuit

wave rectifier. Lower d.c.

output with poor regulation. ‘

Increased ripple at 50Hz not

100 Hz as should be the case.

One diode in bridge short

Mains fuse blown, since

circuit

secondary winding will be

practically shorted every other

half cycle. A resistance check

across each ann of bridge is

required, measuring the

resistance of each diode in

the forward and reverse

direction.

Reservoir capacitor open

Low d.c. output with very

circuit

high valves of a.c. ripple on

output.

Reservoir caacitor short

Fuses blown. D.C. resistance

circuit

ofunstabilized line low in

both directions. .

Error amplifier in regulator

High d.c. output that is

open circuit

unregulated. No control

.

signal for the series element.

Series transistor open

Zero d.c. output. -The un-

circuit base emitter

stabilizedd.c. will be slightly

.

higher than normal since no

current is being drawn.

Reference zener short

Low d.c. output. Possibility
