Multisystem Ignition Analyzer 3.3.6 Main and Secondary Functions display combinations Fig.3- Examples of Main and Secondary Functions combinations 3.4 Measurement Procedures CAUTION To avoid personal injury or damage to the instrument, please check the spark plug wire, distributor cap, ignition coil, ignition module and other ignition system components carefully for damage or leaks. - Page 9 Multisystem Ignition Analyzer 3.4.1 Instrument measuring functions There is the special dedicated mode for the ignition technology of diagnosing and troubleshooting the Coil on Plug and Coil near Plug, and using the spark plug wire system. These dedicated modes compensate the difference in signal strength and waveform patterns between ignition systems.

Page 13: Application Information
Multisystem Ignition Analyzer about 3 minutes of inactivity. Inactivity means: ◆ No buttons are pressed ◆ No measurements are taken 4. APPLICATION INFORMATION 4.1 Taking measurements 1- According to the instructions in “3.4 Measurement Procedures”, select the ignition system to measure. 2- Observe the spark burn time and spark KVolt reading of the display. -
Page 14: Common Causes Of Short Burn Time Readings
Multisystem Ignition Analyzer ◆ Dirty or the damaged spark plug insulator or boot allows the spark “tracking” across the insulator. ◆ Rich mixture. Most likely due to the leaking fuel injector, or the faulty oxygen sensor. ◆ Low cylinder compression pressure. It may be caused by the leaking valves, worn piston ring, blown cylinder head gasket, etc. -
