Battery Undercharged

NOTE: Ensure battery is fully charged and in good condition before performing the following steps. If battery is not at (or near) a fully charged condition, or if its condition is questionable, substitute a known good battery before proceeding.
  1. Check circuit No. 15A (battery ground). Check circuit No. 2B and 2C (fusible link wire) from battery positive to starter solenoid contacts and from starter solenoid contacts to alternator.
  2. Check for parasitic drains by performing parasitic load testing. See PARASITIC LOAD TEST  under ON-VEHICLE TESTING. Check for constant engine running at low RPM. Check for excessive electrical drain.
  3. Using a carbon pile load tester, perform a alternator load test. See BATTERY/ALTERNATOR LOAD TEST (ARBST TEST)  under ON-VEHICLE TESTING. Check for loose or broken drive belt.
