STEilCE-R TEST 91
1.
Connect
RED clip and BLACK clip to the
terminations
indicated in the question.
RED to
the first, BLACK to the second.
2. Start Test 91,04.500
Ohms.
3. Displayed
reading is in ohms. Less than 5 ohms
is continuity.
If the resistance is over 4.509
ohms, STEACE-R displays .9.9.9.9.
WARNING
There
is battery voltage at
the PCB at
all
times.
Failure to disconnect
battery cable
will result in damage to equipment
or injury
to personnel.

NOTE
When checking for voltage or continuity in a harness
connector (steps A2 and A3),
check the wiring at the
connector carefully for broken wires.
Check to see that
the connector pins are not bent, broken, or pushed out of
place.
Check that the connections
are clean and tight.
Use the STUICE-R
in TK
mode
for this measurement.
DO NOT USE THE DCA.
Leave the negative battery
cable off for the measurement.
If
there is an open circuit,
the STUICE-R
will measure close to 500 ohms. If you
don’t have continuity
or voltage, and the wires and
connections
are all OK, then the harness must have a
broken wire.
In this case, you have to replace the
wiring
harness. Replace harness and notify DS maintenance
(chapter 18).
Replace
PCB (para. 44).
