It shows good if the impedance is within the range of
standard values.
The impedance
∞
indicates that the coil breaks.
Remove the spark plug cap. Measure the impedance
between
the primary side wire of the ignition coil and the negative
terminal.
Standard: 0.5-5.5K

2.6 Trigger
* Note
Check the trigger on the engine.

Remove the body guard.
Remove the trigger terminal.
Measure the impedance between the blue/white terminal of
the side wire of the engine and the body GND.
Standard: 100-500
