How is Magneto tested in a small engine?
Small engines can get away with less spark output. This is what gets done first with a suspected magneto issue. Step one is to test the magneto as a system with the Allen Electrical Servicer then if faulty identify and correct the defective components.
Why is there no spark in my ignition?
An ignition module requires some type of external input in order to activate. If your vehicle stalls unexpectedly during operation and will not start again, it is likely because of loose or corroded electrical connections in the ignition module. In this case, check the switch, clean oxidized terminals, and replace broken wires if necessary.
Can a non metallic wire pull apart Magneto?
The conductors can pull apart inside the wire insulation jacket in some cases we have seen. Beware of resistor or non metallic wires, they are a big NONO with early magneto ignition systems as are resistor plugs. If there is spark but no go it could be a fouled plug.
What to do when your engine has no spark?
Insert a spark plug tester into the plug boot and ground it on a piece of metal on the engine. Finally, Have someone crank the engine and watch for spark. Remove one of the coils from the spark plug. Use an extra spark plug. A spark plug tester. Or even a screwdriver in the end of the coil.

What kind of motor does a magneto drive?
It has a 2HP variable speed DC motor and variable width spark gaps. it will drive base or flange mounted magnetos. This is helpful to detect a miss from a short or leakage as well as how hot is hot enough to perform adequately by adjusting the widths of the spark gaps.
What causes PF failure on a magneto test?
Get to the point (s)! Once it is determined that the magneto has low or no output, the next step is the most likely cause pf failure and that is dirty points. Point contacts can fail by accumulation of metal oxides that are hard and do not conduct electricity. Normal wear, moisture and a faulty condenser can cause this.
