b. Turn OFF the VEHICLE MASTER POWER
before
connecting
or
disconnecting any electrical cable or harness.
c. Whenever disconnecting a connector, check it for cleanliness
and broken, bent, or pushed-in pins. Upon discovering any missing or
damaged pins, notify your supervisor.
d. Remove the test probes and jumpers after answering the
questions in each block of the procedure, unless otherwise noted. If
the step in the procedure requires additional adapters and/or jumps,
refer to TM 9-2350-264-20-1 for information on the additional items.
e. When preparing the multimeter for measuring 0 to 5 ohms, have
the RANGE switch set to the lowest position.
CAUTION
THE FOLLOWING STEPS HAVE AN ACC DESIGNATION.
f. When connecting electrical connectors, make sure you have them
fully mated. Hand tighten connectors whenever possible; use plastic
jaw pliers as a last resort only.
Tank electrical connectors have
two types of locking mechanisms. When connecting threaded electrical
connectors, make sure the connectors mate fully by turning the
connector until you feel metal to metal bottoming.
Wiggle the
harness slightly while turning connectors to ensure the connectors
mate fully.
When connecting bayonet type connectors, turn the
connectors until you hear a click.
g. Always look for obvious damage to wire harnesses and all
surrounding components while checking for loose electrical connectors
or making harness disconnections. When you find a wire harness where
the outer shield has sustained damage to the extent that you see the
inner conductors, you must replace it.
Remember to reconnect all
cables and harnesses that you disconnected to get at the connection
you must check.
h. Make sure you have covered all vehicle line replaceable unit
(LRU) test connectors with the metal caps provided, whenever you are
not performing a test.
