Doing some playing around... I mean working on the WD today getting ready for winter. I put the recharged battery and fresh gas in it, but it wouldn't start. It sounded like it wasn't firing, so I suspected the cheap switch I had put in this summer had given up the ghost.

That wasn't it, I had good spark on both sides of the ballast resistor and going to the points; but no spark at the contacts. By now I think the new this summer points, with about five hours on them have somehow burnt up.

I got a flashlight (it was pretty dark in the barn), so I could see what I was doing.

When I opened the points with a screwdriver I saw sparks coming from the spring. It had somehow rotated down to where itr made enough contact with the baseplate of the distributor to ground the current. Once I moved it, the tractor started like it is supposed to.

I have no idea how this happpened; I ran it several times after installing the points, I'm just glad it wasn't -20 with three feet of snow to clear when it happened.

Something to watch out for, I guess.

Robert, If your Tractor is converted to 12V, loose the ballast resistor and install an internal resisted 3.0 ohm coil. Mother Nature plays havoc with ballast resistors. That's probably your problem.....
