I 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. Replace the PCB (para. 4-4). INSTRUMENTS CIRCUIT RESISTANCE AND CONTINUITY 04,500 OHMS STMCE-R TEST 91 1. Connect RED clip and BLACK clip to the indicated terminals in the question. RED to the first. BLACK to the second. 2. Start Test 91,0-4,500 Ohms. 3. Displayed reading is in ohms. Less than 5 ohms is continuity. If the resistance is over 4.500 ohms, STUICE-R displays .9.9.9.9. CONTINUITY (RESISTANCE) MULTIMETER 1. Set the 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). 2-373/(2-374 blank)
