Wave Pattern Observation Points
NOTE:
Condition of wave pattern build-up section and maximum voltage (Refer to abnormal wave pattern examples 1 and 2.)
WAVE PATTERN OBSERVATION
| Condition Of Wave Pattern Build-up Section & Maximum Voltage | Probable Cause |
|---|---|
| Rises from approx. 2V to approx. 4.5V at top-right | Normal |
| 2V rectangular wave | Open-circuit in ignition primary circuit |
| Rectangular wave at power voltage | Ignition power transistor malfunction |
