What is this ceramic thing on my coil?
I bought all new plugs, wires, dist. cap, rotor, condensor, points, etc. and started to put them on the tractor today. Well, almost. I shined up the starter face and it helped a lot as well as shining up the ground cables etc., but there was a lot of frying and sparking and zapping inside the new starter switch I bought, and I imagine it probably now looks like the old one, eg. black and partially melted!
I took off the coil and noticed I didn't have a recognizable condensor on it like on my Cub. That is, assuming I'm correct in assuming that little silver cylinder is the condensor... In its place was this little ceramic block, approximately 1 inch longer than the silver cylinder type and under which there was a wire-wrapped fiberglass element burned in half and corroded near one end.
This thing had wires connected at both ends, one coming from the coil and the others passing on I think to the solenoid on the fuel line and the other up into the dash somewhere (sorry it was getting dark and I couldn't tell exactly where in all that schmoo it was going.)
Any idea what this is, and why I don't have a little silver cylinder on there, and what the heck do I do now?

Allen - that is a ballast resistor.

If you can't fix it with a hammer, you've got an electrical problem.

OK BigDog, I believe you... I still don't know what to do with it
Do I replace it in kind, do I replace it with a newfangled device, or do I leave it out? Do I still install the condensor?
I'm afraid this is my first excursion into the electrical side of the tractor.

A balast resister gives a voltage drop from 12 volts to 6 volts. The coil you have needs 6 volts. You have a 12 volt battery there fore a dropping resister.

or a 12 volt coil. (I'm assuming you are working with a 12 volt system.

Allen, that ballast resistor looks like the one I had on a 1955 Packard. It was bypassed when starting the car, and then in play when the ignition switch was in the run position. Reduced the voltage back to 6 volts for the ignition system. I think you definitely need the resistor and should replace it. There may be a resistance value marked on the shell. . Bill

12V
Yep, this is a 12V system (battery at least is 12V), and I've bought a new 12V coil for the tractor.
The starter is 6V but I don't think that's a problem using it with 12V...
Will everything else in the system be OK if I leave this out and put in the new 12V coil?

I got one at NAPA. They had two different ones, for $56 and for $26, so I got the one for $26...

I put the coil on today, and it says right on the side of it, "12V, No External Resistor Required", and everything's working great.
