Spare Parts and Replacement Procedures 8 - 11
Replacing
Components
Only disassembly procedures are given in this section. Reinstallation
procedures are usually the exact reverse of removal procedures (i.e.,
follow the removal procedures in reverse order to reinstall the
component). Specific instructions are given when this does not apply
exactly, or where special considerations or precautions must be taken
during reinstallation. Applicable portions of Section 5, Installation, may
be helpful. Portions of Section 6, Testing, can be used after reinstallation
to verify proper operation of the rectifier.
Guidelines
Some points are common to all rectifier disassembly work. Please read
this section before using the rectifier disassembly procedures.
DANGER: The following disassembly or reinstallation procedures
MUST be performed only on a rectifier completely disconnected
from the plant battery buses, AND with no input from the ac service
panel connected to the rectifier. The plant control cable, J5A,
should also be disconnected from the CM4 board.
• Remove the rectifier from service per Section 7. After replacing
components, restore the rectifier to service per Section 7. Remove
plastic shields where necessary to access components in the
J85503C-3 rectifier. Refer to Figures 2-2, 2-4, and 8-1 for component
locations.
• Take proper precautions against accidental personal injury or damage
to equipment. Observe warnings given in Section 3 in addition to
admonishments in this section before undertaking any disassembly
or reinstallation procedure on a rectifier.
• The ac service and dc battery buses can be safely disconnected from
the rectifier by following the first eight steps of Section 7, “Remove
Rectifier from Service”; all work must be done carefully because you
are working with live cables at battery bus potentials and current
capabilities. The disconnected charge battery and charge ground
connectors must be taped adequately to prevent them from
contacting each other or any other metal surface. Alternatively, the
dc battery cables from the rectifier can be disconnected at the plant
charge battery and charge ground buses.
• Always make note of the lead connection points (termination points)
before unsoldering or disconnecting them to insure trouble-free
reinstallation. This includes potentiometer leads, or the solderless,
quick-disconnect type connections used on circuit boards, relays,
inductors, transformers, and wire bundles.
• Always disconnect quick-disconnect connections by pulling straight
apart with pliers to avoid bending or breaking the tabs. Do not pull
