WARNING
DISCONNECT NEGATIVE BATTERY CABLE
BEFORE DISCONNECTING AND
RECONNECTING PROTECTIVE CONTROL
BOX/DISTRIBUTION BOX HARNESS.
There is battery voltage at the PCB/distribution
box at all times. Failure to disconnect battery
cable will result in damage to equipment or
injury to personnel.

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 STE/ICE-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 STE/ICE-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, notify DS Maintenance.
Replace PCB, refer to (para. 4-5).
Replace distribution box, refer to (para. 4-5.1).
0-4500 OHMS
STE/ICE-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, 0-4500 ohms.
3. Displayed reading is in ohms. Less than 5 ohms
is continuity. If the resistance is over 4500 ohms,
STE/ICE displays 9.9.9.9.
INTERLEAVE TEST 67 AND 89.
BATTERY VOLTAGE AND DC VOLTAGE
USE CONTROL FUNCTION 06 TO INTERLEAVE
TESTS ON THE STE/ICE-R. DIAL 06, PRESS
THE TEST BUTTON. WHEN PROMPTED BY
THE VTM, DIAL IN TEST 67 AND PRESS THE
BUTTON. WHEN PROMPTED AGAIN, DIAL IN
TEST 89 AND PRESS THE BUTTON. VTM
WILL DISPLAY RESULT FOR TEST 67, THEN 89
THEN 6789, AND THEN REPEAT. SEE TM
