MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION 2. STARTER MOTOR OPERATES, BUT ENGINE CRANKS SLOWLY (Contd) NOTE A voltage reading exceeding 0.2 volts indicates bad connection at starter motor terminal lug 3 and terminal 6 of solenoid lug. 3. Crank engine (TM 9-2320-361-10) and observe multimeter. Test 5. Test starter motor solenoid contact voltage drop. 1. Set multimeter to voltage range that will measure tenths of a volt. 2. Connect multimeter between starter motor solenoid terminal lugs 2 and 3. NOTE A voltage reading exceeding 0.4 volts indicates defective starter motor solenoid. 3. Crank engine (TM 9-2320-361-10) and observe multimeter. Test 6. Test negative cable 7 voltage drop from batteries to starter motor. 1. Set multimeter to voltage range that will measure tenths of a volt. 2. Connect multimeter positive lead to terminal stud on end plate of starter motor and negative lead to frame ground. NOTE A voltage reading exceeding 0.4 volts indicates defective starter motor solenoid. 3. Crank engine (TM 9-2320-361-10) and observe multimeter. Clean and tighten connections WP 0088 00). 1. Replace starter motor and solenoid assembly (WP 0088 00). 2. If malfunction still exists, go to tests 6, 7, and 8. 1. Replace starter motor and solenoid assembly (WP 0088 00). 2. If malfunction still exists, go to tests 7 and 8. TM 9-2320-361-24-1 0012 00 0012 00-16 BATTERY AND CHARGING SYSTEM TROUBLESHOOTING (Contd) Table 2. Starting System Troubleshooting Procedure (Contd).
