Does a magneto need power?
Because it requires no battery or other source of electrical energy, the magneto is a compact and reliable self-contained ignition system, which is why it remains in use in many general aviation applications.
Why are my magneto coils not working properly?
Meaning you have a wire that has power from the battery that is touching the frame or some sort of ground. It also could be something in a one of the lights housings that is causing a short as well. It has nothing to do with the magneto or stator coils as they don’t get power from the battery.
Why are there no spark plugs on my magnetos?
These faults do not necessarily occur instantaneously, they may develop over time leading to a gradual deterioration of the spark output. The voltage generated across magneto coils is quite high, in the order of 20,000 volt if no spark plugs are in place. The coils are, of course, designed for this pressure but no insulation is perfect.
What do you use to keep magneto coils in place?
A strip of polyester tape is pierced with a sharp point and fed over the tinned copper wire to both insulate and to help hold everything in place. The tinned copper wire spout is then insulated with high temperature sleeving – we use a double layer – again held in place with more polyester tape.
How does primary winding work on a magneto coil?
Primary winding involves passing the end of the wire through the hole in the side covering and revolving the core to make a layer of wire across to the other side.
Do you need an external coil for a magneto?
No external coil is required in this case because the winding of the magneto itself becomes the inductor and the circuit is simplified, also the IGNITER is normally closed and trips open only when a spark is required. The timing of the magneto and the ignitor is important so that its “peak” output occurs at the igniter “break” time.
Why are my magneto coils not working on my bike?
Magneto coils: as seen in the video above, for vintage bikes this is the most common reason for not having spark, the insulation has broken down so current induction cannot occur. Essentially this is the resistance that the test performs. We were unable to load Disqus Recommendations.

How does a magneto ignition work in a gas engine?
The MAGNETO is simply a magnet, with a coil of wire revolving between its poles, the coil being provided with a suitable means whereby the current generated is conducted off to the engine igniter, the points of which are alternately opened and closed at the proper time.
