Default 2 1/4 Galloway runs when it shouldn't

Most engine starting questions are why an engine won't start. This post is why did it run. I went to start my 2 1/4 Galloway with batttery and coil, lubed it up, checked the oiler, primed and away she went on first pull - like usual. Problem? I forgot to hook up the coil, I had my battery charger hooked to the ignitor and grounded on the engine with the coil in my shop. The charger showed 0 amps except when the ignitor tripped and then it pegged for a second, no over amp circuit breaker popping. I started it several times and when I went to put it up, no coil, duh.

Because there was still a spark , all the coil does is increase inductance, you still have 'some' inductance without it so it could work no problem, potential difference will still span a gap when called upon, besides the battery charger will have coils anyway in the transformer . Might not be great for the igniter points though.

Your charger is in fact a coil? It only puts out 12 volts or so, and probably less than 10 amps? You are lucky you didn't run it for long, that kind of abuse will burn out the diodes in the charger. Also, running for any length of time will heavily burn the points!

Yes, the charger is acting as a coil, kind of. The charger likes to see something like a battery across it, something that looks like a big capacitor. Without the battery (and without going into a lot of electromagnetic theory) the charger is having one heck of a Tesla-esque spaz attack, especially when the points open, and you can generate one pretty good spark. You can also fry the charger. I was running a Fairbanks once this way - ran great until all the smoke came out of the charger. It stopped running about the time flames came out of the charger.
