Electrical: no spark

[ronark]

I decided to start the champion engine today, haven't started it in over a year. Turned over ok, but got no spark. I had voltage at points, but could see no spark at points when they broke. I had very weak spark at coil wire, almost non existant. I am guessing either bad coil or condensor. Any ideas out there?

Condenser?

Try cleaning the contact area of your points.I have 2 motors that after setting that long I have to run a strep of sand paper between the contacts before the points will make a good enough ground to spark like thay should.

My guess would be a bad condenser, but check the points anyway. Bud

That'a a good idea, except sandpaper is comprised of silicon carbide, one of the best insulators on earth. That's why they used to make point files. If you do use sandpaper, fold it inside out after and thoroughly clean any speck of dirt between the contacts.

I don't use sandpaper, I use a piece of grocery bag (brown) paper.

Got it started, had to change the coil finally. I tried new points and condenser first. Hated to replace the coil as it was original coil. Was able to use old bracket after prying it loose from the old coil. Thanks for the replies.

The petronics unit I bought was faulty, but I liked the Flamethrower coil that came with it....until I noticed the hood had rubbed a hole in it. Back to points and regular coil!
