They don't mention what voltage to use, I am gonna guess 3V or two D cells would do it. Something that I will have to try. I made a tool for checking automobile coils, when cars still had ones that were testable. It was just a switch with a capacitor wired across it. You disconnected the points or blocked them open and hooked the leads from the switch across the coil. They you turned on the ignition and cycled the switch on and off. Spark = OK, no spark = bad. Never thought to try it with a small engine, never had any idea what voltage the magnets would generate.

A quick test I use to check that the coil-condenser assembly can produce spark with a
single D size 1.5 volt battery and a couple jumper leads.
For a simple demo I recommend youtube video;

For a simple demo I recommend youtube video; How to check magnetos with a flashlight battery revisited. by : Ken Bohn Further testing has revealed that 1.5 volts will produce spark on a normally gapped plug (.025")...BUT, A properly functioning coil-condenser assembly must be able to produce spark on a test plug (ground strap removed). .250" ...Two D cells (3.0 volts) is required to jump the gap on a test plug. |

I made a tester using a Model T Ford vibrator coil. It's pretty handy to do a quick coil test for points ignition. youtu.be/8XK01HjV1lw |
