Section VI. CAPACITOR, DIODE, AND CIRCUIT CARDS
Disconnect capacitor (58, figure 4-1)
leads and remove capacitor from clip
With capacitor tester, check capacitor
(58) for 40 microfarad capacitance.
Replace capacitor if it does not meet
Install new capacitor (58) in clip (60).
Solder capacitor leads.
Disconnect one lead of diode (27,
figure 4-1) from terminal board (30).
Connect ohmmeter (Rx100) across
diode and note reading.
Reverse ohmmeter leads to diode and
A good diode will read high resistance
in one direction and low resistance in
the other direction. A shorted diode
will read full scale both ways. An
open diode will read infinity (no
reading) in both directions. Replace
diode as required.
Replacement. Reconnect leads of new
diode (27) on terminal board (30).

Testing. Test individual circuit cards for
obvious points of continuity using an
Repair. If breaks on circuit card are minor
or few, repair by soldering an insulated
piece of wire between broken points of
continuity. If circuit card is badly burnt or
breaks are irreparable, repair card by
