[AJD] magneto question

[greg at theoldtractorcompany.com]

Just had one that the "new" condenser up and quit. Funny how vintage parts could work for 
decades and sometimes today's hi-tech parts can't make it a year

>Hello folks - I have what may be a pretty basic magneto question.  I've got
>a '38 JD 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?

>Thanks!
