WARNING
Soldering iron can cause severe
burns to personnel and start fires.
Observe all safety precautions
when using soldering iron. If injury
occurs, seek medical aid.
Discharge all capacitors by ground-
ing prior to removal. Capacitors can
hold an electrical charge and create a
dangerous potential for electrical
shock. If injury occurs, seek medical
aid.
CAUTION
Identify each capacitor lead during removal
to ensure correct polarity during installation.
Accidental polarity reversal will damage ca-
pacitor and/or other internal components of
GCU.
NOTE
If removing capacitor C23, perform step a.
If removing capacitors C20, C21, or C22,
proceed to step b.
a. Desolder lead (1) from terminal one and lead
(2) from terminal two of capacitor C23 (3).
(1) Slide sleeving (4) back from solder termina-
tion and remove coating from leads (1) and
(2). Use brush (item 35, App F).
(2) Identify and desolder leads (1) and (2) from
