Very interesting forum.
I'm glad my "poor Mr. Oersted" DID get something named for him!
I have been looking for the past few days through various auto-repair books, trying to find a good engineering-type explanation for the phenomenon we are all writing about. Have found very little that goes beyond the "current wants to continue across the arc" explanation, and that the arcing current is large enough to burn the points. I did think of a kind of poor-man's analogy: Remember those water pipes that thumped when you turned off the water, until you either put some kind of tight hangers on them OR installed a tee and a piece of pipe to absorb the shock? The tee was full of air, and acted as a shock absorber by letting some of the water that was suddenly shut off escape briefly into the "shock absorber." I don't suppose this is a good engineering explanation, but it helps me, at least, the function of the condenser, a sort of electrical shock absorber.
Electrical engineers, please, please forgive the
amateur analysis. You're probably wringing your hands by now!

Today's Featured Article - The Cletrac General GG and the BF Avery A - A Bit of History - by Mike Ballash. This article is a summary of what I have gathered up from various sources on the Gletrac General GG and the B. F. Avery model A tractors. I am quite sure that most of it is accurate. The General GG was made by the Cleveland Tractor Company (Cletrac) of Cleveland, Ohio. Originally the company was called the Cleveland Motor Plow Company which began in 1912, then the Cleveland Tractor Company (1917) and finally Cletrac. ... [Read Article]
