I appreciate the answer you gave, however my cub has a j4 magneto with an internal coil that doesn't have the two wire set up you have shown. how do I test my coil?
additionally how do I test for a bad condenser?

Google is or can be your best friend. I found my original link via google. Just google IHC J4 magneto test and go from there.

condensers are capacitors. test them with an ohm meter.
short the pigtail to the body to discharge it.
set a meter to Rx1
put leads on the pigtail and body. On an analog meter, the needle will swing from 0 ohms to infinite. On a digital it will go from a low reading, probably auto range a bit, then indicate infinite.
Condensers that read infinite all the time are open, ones that read 0/low and never increase are shorted.
