NOTE
Ensure capacitors are positioned in correct polarity before soldering to printed
circuit board.
(2) Secure capacitor circuit board with two screws.
(3) Install heat sink filter assembly described in paragraph 6-25b.
6-27. Filter Capacitor C1 through C6 Removal and Replacement.
Perform the following procedure to remove and replace any capacitor C1 through C6 (see figure FO-22).
a.
Removal. Remove any capacitor C1 through C6 as follows:
(1) Remove heat sink filter assembly described in paragraph 6-25a.
(2) Remove filter capacitors circuit board by removing two screws. (This allows access to remove any
capacitor C1 through C6.)
(3) Unsolder and remove capacitor.
b.
Replacement. Replace any capacitor C1 through C6 as follows:
(1) OBSERVE POLARITY and solder capacitor leads.
(2) Replace filter capacitors circuit board with two screws.
(3) Install heat sink filter assembly described in paragraph 6-25b.
6-28. Rectifiers CR1 through CR4 Removal and Replacement. Perform the following procedure to remove and
replace any rectifier CR1 through CR4 (see figure FO-22).
a.
Removal. Remove any rectifier CR1 through CR4 as follows:
(1) Remove heat sink filter assembly described in paragraph 6-25a.
(2) Remove two screws securing filter capacitors circuit board. (This will allow access to remove and
replace any rectifier CR1 through CR4.)
(3) Unsolder wires connected to rectifier.
(4) Remove nut, wire lug (with wire attached) and insulated washers, and remove rectifier.
