I think we all have this saved, should modify it.

Opps sorry this one. You can see some other correct numbers on here though.

Great looking motor there! you will love running it. Be careful with the short tiller handle while turning or going over waves. My V45 likes to pull the tiller out of my hand if it catches me off guard, so hold onto it good in rough water.
I have reused the tar, and melted it back in using a propane torch set low. i’m sure it’s nasty stuff, so do it outside or ventilate the area.
When you test the coils, be sure to test from one end of the secondary [spark plug lead] to the end of the other secondary lead of the same coil. Someone correct me if I’m wrong but I think these are the same as a PO15 coil ? Not sure on the condensers but some of the other guys will no for sure. If you need a coil, let me know, as I can probably come up with one.

It’s off my ’34 F-70 which is sporting the 200 muffler.

Here’s a slightly edited version of that caps table so you can erase, copy and paste.

Jerry,

I did test the coil from one spark plug lead to the other spark plug lead(same coil). The double coil testing kind of threw me for a loop in the beginning.

Thanks for all the great feedback. Now I can get it done and have the correct condenser.

I still wanted to make sure that the 8-9 ohms on the coils are an acceptable reading.

8-9 ohms? That should be 8-9 K (thousand) ohms across the secondary windings! 😀

Another amended table. . . 🙄

For some reason, 7,000 ohms sticks in my mind for the secondary. Keep in mind that temperature will also affect your reading. I would be surprised if those coils are bad. Johnson ignition coils are about bullet proof, at least in my experience. Tomorrow I’ll throw a meter on one of mine and see what it shows, then report back.

Yes, I don’t know much about this electric stuff. 8000-9000 ohms, I stand corrected. I think it is a click or two over on the meter and it reads different stuff. I could read that funky upside down ohm symbol and that seemed to be enough for me!

I was getting same readings(8-9k ohms) when whole motor was assembled and spark plug wires were attached to spark plugs.
Taking the meter leads to the two top spark plug wires or two lower spark plug wires depending on which coil I was testing. Kind of cool.
