TROUBLESHOOTING
CHARGING SYSTEM
A battery that does not hold charge might be a symptom of:
1) current loss (see paragraph "Current loss at the battery");
2) incorrect voltage (see paragraph "Regulated voltage");
3) no continuity in generator (see paragraph "Generator stator windings resist-
ance inspection");
4) incorrect no-load performance of generator (see paragraph "Generator no-
load performance")
5) voltage regulator malfunction (see paragraph "Voltage regulator/rectier
inspection")
- a battery overload indicates:
1) faulty voltage regulator (see paragraph "Voltage regulator/rectier inspec-
tion");
2) faulty battery (see paragraph "Current loss at the battery").
STARTING SYSTEM
If the starter motor does not start, this might be a symptom of:
1) faulty solenoid starter (see paragraph "Solenoid starter inspection");
2) loose starter motor cable;
3) faulty starter motor (see paragraph "Starter motor inspection");
4) at battery (see paragraph "Battery charger").
ELECTRONIC IGNITION SYSTEM
A weak or missing spark might be a symptom of:
1) incorrect connections in the electrical system;
2) faulty spark plug or wrong heat rating or incorrect spark plug gap (see para-
graph "Spark plug");
3) faulty ignition coil (see paragraph "Coil windings resistance inspection");
4) faulty spark plug cap (see paragraph "Coil windings resistance inspec-
tion").
