Re: [EVGRAY] Sven, this is old style 3 pole magneto coils for Outboard Marine outboards!

Body

same applies to coil bangers to obtain OU  effects and also RV & EM-PM RVs genemotors ... call it the sweet point of the device !

 Sven, this 3 pole coil design was used for many years by Outboard Marine Corp 40s up to the 70s in the two cylinder magnetos.  I had a magneto test bench where I could experiment with the careful timing adjustments of the breaker points (before breakerless solid state commutation).  by careful adjustment of breaker gap/timing you could get magneto operating at peak of resonant curve in the "Ultra high Q" region!  At idle, (300 RPM) a very well tuned magneto of this design would yield a good one inch bright blue arc.  The condenser for this type of coil was .026mfd which was a "perfect match" to the impedance of the iron core coil.  I had various values of condensers (capacitors) but only the proper value would yield maximum performance!
