  3. Turn ignition switch to OFF position. Attempt to rotate negative battery cable connector clockwise with light finger pressure. If negative connector rotates, go to next step. If negative connector does not rotate, go to step  5 .
  4. Using an INCH lb. torque wrench, record torque value while loosening negative battery cable bolt. If torque is equal to or greater than 88 INCH lbs. (10 N.m), go to step  6 . If torque is less than 88 INCH lbs. (10 N.m), go to next step.
  5. Disconnect negative battery cable and go to step  9 .
  6. Disconnect negative battery cable. Inspect battery and cable terminals for corrosion and defects. If problem exists, repair as necessary. After repair, go to next step.
  7. Attempt to rotate positive battery cable connector clockwise with light finger pressure. If battery cable rotates, go to next step. If battery cable does not rotate, go to step  9 .
  8. Using an INCH lb. torque wrench, record torque value while loosening positive battery cable bolt. If torque is equal to or greater than 88 INCH lbs. (10 N.m), go to step  10 . If torque is less than 88 INCH lbs. (10 N.m), go to step  11 .
  9. Disconnect positive battery cable and go to step  11 .
  10. Disconnect positive battery cable. Inspect battery and cable terminals for corrosion and defects. If problem exists, repair as necessary. After repair, go to next step.
  11. Clean and wire brush lead face of both battery terminals and metal contact surfaces on both cable connectors. Remove bolts from both battery cable connectors and inspect for corrosion and defects. If problem exists, repair or replace as necessary. If battery and cables terminals are clean and in good condition, go to next step.
  12. Connect positive battery cable to battery and tighten bolt to 13 ft. lbs. (18 N.m). After repair, go to next step.
  13. Connect negative battery cable to battery and tighten bolt to 13 ft. lbs. (18 N.m). After repair, go to next step.
  14. Ensure all electrical loads are off. Follow manufacturers instructions and install Battery Tester (J-42000) to vehicle battery. Follow any instructions displayed on Battery Tester, EXCEPT add 100 to AGM Battery's CCA rating when prompted to enter CCA into tester. DO NOT make this modification for other battery types. If Battery Tester passed battery, go to next step. If Battery Tester did not pass battery, go to step  16 .
  15. Press CODE button on Battery Tester. Record displayed code on vehicle repair order for warranty purposes. Go to next step.
  16. If J-42000 battery tester displayed result of GOOD-RECHARGE or CHARGE & RETEST, charge battery. If J-42000 battery tester did not display result of GOOD-RECHARGE or CHARGE & RETEST, go to next step.
    17. NOTE: If battery was tested in vehicle with battery cables connected, disconnect cables and install proper adapters. Repeat test according to tester instructions for testing out of vehicle. Replace battery only if the second test shows a REPLACE or BAD CELL-REPLACE result. Use test code from second test.
  17. Press CODE button on Battery Tester. Record displayed code on vehicle repair order for warranty purposes. Replace battery.
