Digital Multimeter Cen-Tech

Magneto Testing- Take a voltmeter or multimeter
and adjust it to the Ohms setting at 20k.
Ohms measures the resistance across a circuit.
Check voltmeter across the following wires:
Blue wire to the White wire of the magneto.
The resistance should be 0.25 to 0.40. New magnetos read 0.31.
White wire to Black wire should read 0.0.
Blue wire to Black wire should read close to 0.31.
If your reading is far off from this,
then the magneto is to blame for bad spark.
CDI Testing- Run the voltmeter at the same 20k setting.
Check voltmeter across the following wires:
From the inside of the spark plug boot to the Black wire of the CDI.
Your reading should measure 2.0 – 2.7. A new CDI will read 2.3.
Spark Plug Boot to the Blue wire there should be no change, or 1.0.
Blue wire to Black wire there should be no change, or 1.0.
