14-38. RECTIFIER (CR1) AND CAPACITORS (C1 AND C2). - continued
(2) Capacitors (C1) and (C2).
(a) Using a multimeter set to read high resistance, place positive lead to positive terminal and negative
lead to negative terminal of capacitor.
(b) If capacitor is good, multimeter needle should move rapidly to top of scale then slowly return to zero.
The capacitor is internally short circuited if needle moves to top of scale and stays there. The
capacitor has an open circuit if the needle does not move.
NOTE
Replace rectifier (CR1) and capacitors (C1) and (C2) if any one component is defective.
d. Install.
(1) Slip heat shrink tubing (7) over capacitor (5) and (6) leads. Heat to shrink in place.
(2)
Solder wire and capacitor leads in place using tags and wiring diagram.
Remove tags.
(See
(3) Secure in place using screw (1), lock washer (2), and flat washer (3).
NOTE
FOLLOW-ON MAINTENANCE:
Install motor controller assembly (para 4-37).
Install logic box assembly (para 4-36).
Install control assembly (para 4-34).
Connect power at power source.
