Inspect connector pins/sockets for damage,
corrosion, and serviceability. Check that
connector pins are not pushed back and
are capable of making good contact.
CONTINUITY TEST
(1)
Remove PDP cover (para 16-2).
(2)
Remove relay K31 from PDP.
(3)
Set multimeter to ohms.
(4)
Connect positive (+) probe of multimeter
to connector J130 socket J.
(5) Connect negative (-) probe of multimeter
to relay K31 terminal 87 on PDP and note
reading on multimeter.
(6) If continuity is not present, go to step 6
of this fault.
WARNING
Remove rings, bracelets, watches, necklaces,
and any other jewelry before working around
vehicle. Jewelry can catch on equipment and
cause injury or short across electrical circuits
and cause severe burns or electrical shock.
VOLTAGE TEST
(1) Set multimeter to volts DC.
(2) Connect positive (+) probe of multimeter
to relay K31 terminal 30 on PDP.
(3) Connect negative (-) probe of multimeter
to ground.
(4) Position main light switch to SER DRIVE
(TM 9-2320-366-10-1) and note reading
on multimeter.
(5) If 24 VDC is not present, repair wire 1956
from K31 terminal 30 on PDP to circuit
breaker CB44 terminal 6 (para 2-45) or
replace WTEC II dashboard cable
assembly (para 7-10) or WTEC III
