Kyle: The magnets might have lost their magnetic power. You need to locate someone who specializes in mag repairs..Good Luck...Joe Hardisky  Ryman farm Dallas, PA

> Hello folks - I have what may be a pretty basic magneto question.  I've got a '38 John Deere B with a Wico C mag.  It's a project tractor that I got running several years ago, but since then, it has been sitting undisturbed but out in the elements - though I have kept the magneto covered and protected.  I decided to start doing some more work on the tractor recently and found that it does not spark anymore.

> To get it running back then, I had purchased a rebuilt magneto which of course worked just fine then.  It has less than an hour's worth of run-time on it, so is essentially still brand new.  I pulled the cap and everything looks clean as a whistle, no burn marks, no pitting, no corrosion, nothing that would indicate an obvious problem.  I'm wondering what sorts of issues can arise from non-use that would cause a brand new mag to quit working?  (I do know the problem has to be in the mag and not in the plug wires or plugs because I swapped out those items from my running Model AW and didn't get any spark either.)

> Also, to test the mag when it is not installed on the tractor, is it ok to just ground a wire to the mag body and flip the impulse over by hand?  Or is that not going to work or is it inadvisable?
