down until lock (arrow, 25) snaps into place.
e. Noting correct labeling and position, reconnect all cables.
3. Replace diode V6:
a. Record labeling and position of cables (40) to diode V6 (22) at terminals A1 and A2.
b. Disconnect cables (40).
c. Pull Diode V6 (22) off double-sided adhesive tape on load contactor K1 (20).
d. Firmly seat diode V6 (22) on double-sided adhesive tape on load contactor K1 (20).
e. Noting correct labeling and position, reconnect cables (40) to Diode V6 (22) at terminals A1 and
A2 and tighten screws (41, 42)
