I WARNING I 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 harness or PCB (para. 4-4). STARTER CIRCUIT RESISTANCE AND CONTINUITY 04,500 OHMS STEIICE-R TEST 91 1. Connect RED clip and BLACK clip to the terminals indicated in the question. 2. Start Test 91, o-4500 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 I 1. Set the voltmeter to an ohms scale of about 1,000 ohms. 2. Connect the RED and BACK 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). 2-281
