Hi,

I'm trying to test the Magneto/Coil on my Honda Mower HRX2172HMA Maga 1508359. The Magneto is a Phelon, part # 30500-ZOJ-0032. I can't find the specs for the resistance or the air gap. I tested the resistance.
Primary reading is 7.3 ohms
Secondary reading is 14.5 k ohms
1. Can anyone give me the specs for this magneto and or let me know if this seems to be reasonable readings?
2. Can anyone give me the air gap setting ( besides using a business card)?

Thanks,
Keith

Ignition coils (magnetos) do not give accurate readings on a tester unless you have really high dollar tester.
They either produce spark or they do not, or they heat up and fail.
unplug the kill wire that is hooked to it, and try to start it. if it starts with that kill wire unplugged, the kill wire or switch has an issue. if no spark with the kill wire unhooked, bad coil. air gap, a business card will do.
