CONTINUITY TEST
NOTE
Inspect connector pins/sockets for damage,
corrosion, and serviceability. Check that
connector pins are not pushed back and
are capable of making good contact.
Use care when testing electrical connectors.
Do not damage connector pins or sockets
with multimeter probes. Failure to comply
may result in damage to equipment.
CAUTION
(1) Remove three screws from PDP.
(2) Remove three screws and washers from PDP.
(3) Lift PDP outward to gain access.
(4) Disconnect connector P51 from connector
J51.
(5) Set multimeter to ohms.
(6) Connect positive (+) probe of multimeter to
PDP, where WTEC III relay K25 terminal 87
was removed.
(7) Connect negative (-) probe of multimeter to
connector J51 pin 2 and note reading on
multimeter.
(8) If continuity is not present, repair wire 490
from WTEC III relay K25 terminal 87
to connector J51 pin 2 (para 2-40) or
replace WTEC III dashboard cable
assembly (para 7-11).
