b. Remove coating from leads (5). Use brush
(item 35, App F).
c. Desolder leads (5) from capacitor (6).
(1) Identify and desolder leads (5) from capacitor
C20, C21, or C22 (6). Use soldering iron
(TM 55-1500-323-24).
d. Remove conformal coating from generator
control unit (7).
(1) Reduce coating around capacitor C23 (3),
