 POOR CHARGING (BATTERY OVER DISCHARGING OR OVERCHARGING)
 Undercharging

 Inspection/Adjustment                   Symptom                   Probable Cause

 Start engine and test
 limit voltage of battery

 Overcharging

 Inspection/Adjustment                   Symptom                   Probable Cause

 Measure battery limit
 voltage with an electric
 tester
                                                                   Faulty battery

 Check resistance
 between regulator/
 rectifier terminals
