IGNITION SYSTEM
TROUBLESHOOTING
No spark at plug. (TOOL : PVA MUITI TESTER)
UNUSUAL CONDITION PROBABLE CAUSE (CHECK IN NUMERICAL ORDER)
1. The multitester impedance is too low.
2. Cranking speed is too slow.
-
Battery is undercharged
3. The sample timing of the tester and measured pulse were not
synchronized. (System is normal if measured voltage is over the
standard voltage at least once.)
4. Poorly connected connectors or an open circuit in ignition system.
5. Faulty ignition coil.
6. Faulty ECU unit (in case when above No. 1~5 are normal).
1. Incorrect peak voltage adaptor connections.
2. Faulty ignition switch.
3. Loose or poorly connected ECU unit connector.
4. Open circuit or poor connection in ground cord of the ECU unit.
5. Faulty peak voltage adaptor.
6. Faulty ECUunit (in case when above No. 1~6 are normal).
1. Faulty spark plug or leaking ignition coil secondary current ampere.
2. Faulty ignition coil.
1. The multitester impedance is too low.
2. Cranking speed is too slow.
-
Battery is undercharged (or operating force of the kick starter is
weak).
3. The sample timing of the tester and measured pulse were not
synchronized.(System is normal if measured voltage is over the
standard voltage at least once.)
4. Faulty pulse generator (in case when above No. 1~3 are normal).
1. Faulty peak voltage adaptor.
2. Faulty crank position sensor
Low peak voltage.
No peak voltage.
Peak voltage is normal, but no spark
jumps at plug.
Low peak voltage.
No peak voltage.
