TM 9-2320-280-20-1 REFERENCE  INFORMATION 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. Check these cables; Starter negative cable - STE/ICE-R test 69 Wire 68, connecting the batteries together. Test point is the positive battery post. Wire 49A, connecting battery to power stud. Test point is the power stud. Wire connecting battery to shunt (50A). Test point is the positive battery post. Power stud to starter motor (6A). Test point is the power stud. Replace or repair cables, refer to (para 4-73). STARTER  CIRCUIT STARTER NEG. CABLE VOLTAGE DROP STE/ICE-R TEST 69 1. Start Test 69, starter negative cable voltage drop. 2. Displayed reading is in volts. The cable voltage drop should be less than 0.25 volts max. 0-45 DC VOLTS STE/lCE-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. 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. 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. 2-271
