[AT] Strange Magneto event today.

[Dean VP]

 Thanks Phil. After my starter fiasco I of all people should be making sure the grounding is good. What part of getting hit over the head with a hammer is good? The part when it ends.

I think you have already figured this one out, Dean. Like Farmer says, "Check the grounds". :o)

Is there anything in or around the shop that could have abruptly demagnetized the magnets...some of the older 'permanent magnet' metal recipes weren't all that permanent, although I never heard of one getting de-magged so abruptly!

 Was helping a friend today testing out some carburetors and Magneto's on his 1936 JD B. A very strange thing occurred. I was in charge of clean ing Magneto's up and getting them to the point that they would deliver spark manually on the bench. Then we would install them on a tractor and get the tractor running. I went though one Magenta pretty thoroughly and was getting really good spark out of both ports on the bench. Install it on the tractor absolutely no spark.   Could hear a really good impulse. We tried tightening it up tighter and also loosening it up. No change ...no spark.  Blew me away I was getting really GOOD SPARK MANUALLY NOT MORE THAN A FEW MINUTES BEFORE. W hat in the sawmill would cause something like that.  The only thing we didn't check was to see if the Magneto was getting grounded properly to the governor.  That is the only thing I can think of right now. What other reasons would cause this strange event???  Really weird.
