STARTER CIRCUIT REFERENCE INFORMATION TM 9-2320-280-20-1 STARTER AVERAGE CURRENT STE/lCE-R TEST 71 1. Start Test 71, starter average current. 2. Displayed reading is in amps. The starter should draw at least 200 amps with a peak of over 400 amps. BATTERY CURRENT MULTIMETER 1. Set the voltmeter to a DC volts scale of about 1 volt. 2. Connect the BLACK lead to the battery side of the current shunt and the RED lead to the other end of the current shunt. 3. Current shunt voltage is proportional to battery current, 100 millivolts. 1000 amps. To get current, multiply millivolts x 10. BATTERY VOLTAGE STE/lCE-R TEST 67 1. Start Test 67, battery voltage. 2. Displayed reading is in volts. Batteries should be 23-25.5 volts. Batteries voltage will drop when glowplugs turn on. BATTERY 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 reed the correct scale. 2-267
