a. Removal. See figure 4-28.
Rotating parts and lethal voltage levels are used in operating the FDECU. Be sure
power source is disconnected. Injury or death can occur if connected to power
(1) Shutdown the FDECU per paragraph 2.4 and disconnect main power cable from power source.
(2) Loosen eight captive screws (1) and carefully pull the electrical assembly (2) out.
(3) Turn to release three latches (3) and open power box assembly cover (4).
Each capacitor is mounted in the same manner and the following procedures can
be used for any of them. The quantities given are for one capacitor only.
(4) Remove two nuts (5), lock washers (6), flat washers (7), and bracket (8). Discard lock washers.
Capacitors can store electrical power for extended periods of time after being
disconnected from power supply. A bleed resistor is connected across the
capacitor terminals to discharge this power more quickly. Do not touch capacitor
terminals for the first five minutes after the power has been disconnected.
(5) Carefully pull cap (9) back to expose capacitor (10) terminals then tag and disconnect wire leads and
