EXAMPLES OF ABNORMAL WAVE-
FORMS
AKX00280
Example 1
• Wave characteristics
Spark line is high and short.
• Cause of problem
Spark plug gap is too large.
AKX00281
Example 2
• Wave characteristics
Spark line is low and long, and is sloping.
Also, the second half of the spark line is distorted.
This could be a result of misfiring.
• Cause of problem
Spark plug gap is too small.
AKX00282
Example 3
• Wave characteristics
Spark line is low and long, and is sloping. How-
ever, there is almost no spark line distortion.
• Cause of problem
Spark plug gap is fouled.
AKX00283
Example 4
• Wave characteristics
Spark line is high and short.
Difficult to distinguish between this and abnormal
waveform example 1.
• Cause of problem
Spark plug cable is nearly falling off (Causing a
dual ignition).
AKX00284
Example 5
• Wave characteristics
No waves in wave damping section.
• Cause of problem
Layer short in ignition coil.
