WARNING   TM 9-2320-280-20-1 REFERENCE INFORMATION Change 1           2-293 VOLTAGE MULTIMETER 1. Set the voltmeter to a DC volts scale of at least 40 volts. 2. Connect the RED lead to positive and the BLACK lead to negative. 3. Be sure to read the correct scale. CONTINUITY (RESISTANCE) MULTIMETER 1. Set the voltmeter to an ohms scale of about 1000 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). Check the wires and connections at both ends for broken wires or any kind of bad connection. Repair whatever you can.  If the wires and connections seem OK, you have to replace the harness. REAR OF ROTARY SWITCH 11A 29A B R S STARTER CIRCUIT Repair wiring or replace harness, refer to (para. 4-85). Replace rotary switch, refer to (para. 4-7). 0-45 DC VOLTS STE/ICE-R TEST 89 1. Connect RED clip to the indicated test point, BLACK clip to negative or ground. 2. Start Test 89, DC volts. 3. Displayed reading is in volts. 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.” 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. 14A
