CAUTION
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.
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.

(1)
Set multimeter to ohms.
(2)
Connect positive (+) probe of multimeter
to connector P119 pin p.
(3)
Connect negative (-) probe of multimeter to
connector P119 pin r and note reading on
multimeter.
NOTE
A good turbine speed sensor
will return a reading of 200-400
ohms resistance as follows:
a.
200 ohms at -40°F (-40°C).
b.
300 ohms at 68°F (20°C).
c.
400 ohms at 230°F (110°C).
(4)
Connect negative (-) probe of multimeter to
all other pins in connector P119 and note
reading on multimeter.
(5)
Connect negative (-) probe of multimeter to
ground and note reading on multimeter.
(6)
If 200-400 ohms resistance is not present
in step 4, or continuity is present in step 5
or step 6, notify DS Maintenance.
(7)
If 200-400 ohms resistance is present in
step 3, and continuity is not present in
step 5 or step 6, replace WTEC II TEPSS
(para 8-2).
(8)
Connect connector J115 to WTEC II
TEPSS.
(9)
Install instrument panel assembly (para
7-15).
(10)
Connect connector P119 to connector
J119.
(11)
Position front grille on cab with washer
and screw.
(12)
Position two washers and screws in front
grille.
(13)
Tighten screw to 48-60 lb-in. (5-7 N·m).
(14)
Tighten two screws to 24 lb-in. (3 N·m).
(15)
Clear diagnostic codes (para 8-4).
