TM 9-2320-387-24-l REFERENCE INFORMATION STARTER CIRCUIT Don’t forget that your vehicle batteries are disconnected. so you can’t run the STEACE-R from the DCA. You have to use the power cable and connect directly to the batteries. When the resistance is too high for STUICE-R to measure, as in the case of an open circuit, STEXE-R displays .9.9.9.9. Repair wiring or replace harness (para. 4-80). Check the wires at the connectors for shorts. If there are no visible shorts, you have to replace the harness. I Repair wiring or replace harness (para. 4-80). -1 Replace starter (para. 4-11). PCB BODY CONNECTOR RESISTANCE AND CONTINUITY 04,500 OHMS STE/lCE-R TEST 91 1. Connect RED clip and BLACK clip to the indicated test points in the question. RED to the first, BLACK to the second. I 2. Start Test 91,0-4.800 Ohms. 3. Displayed reading is in ohms. Less than 5 ohms is continuity. If the resistance is over 45OCl ohms, STEIICE-R displays .9.9.9.9. CONTINUITY (RESISTANCE) MULTIMETER I 1. Set me voltmeter to an ohms scale of about 1.OOO ohms. 2. Connect the RED and BLACK leads to the connections stated in the question. 3. Be sure to read the correct scale. Less than 5 ohms indicates continuity. For an open circuit, the meter should peg full scale (needle all the way to the left). 2-265
