TM 9-2320-387-24-l \ REFERENCE INFORMATION ALTERNATOR INTERLEAVE TEST 67 AND 68 BAITERY VOLTAGE AND DC VOLTAGE I USE CONTROL NNCTION 66 TO INTERLEAVE TESTS ON THE STEIICE-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 68 AND PRESS THE BUTTON. V-TM WILL DISPLAY RESULT FOR TEST 67. THEN 68, THEN 6768, AND THEN REPEAT. SEE TM 94910-571-12&P FOR MORE INFORMATION. I 0 II . . - -I i WARNING Disconnect negative battery cable before disconnecting and reconnecting PCB harness. INTERLEAVE TEST 67 AND 89 BATTERY VOLTAGE AND DC VOLTAGE USE CONTROL FUNCTION 06 TO INTERLEAVE TESTS ON THE STEACE-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 94910-571-12&P FOR MORE INFORMATtON. RESISTANCE AND CONTINUITY 04,500 OHMS 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. - -a 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). 2-207
