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

I've notice on several engine flywheels there are 3 PMs,  small N, large S, small N. the middle one is wider
the coil gets N-S then S_N or a full sine wave
Outboard Marine used a two magnets (N-S) imbeded in flywheel with a "E" 
iron coil frame which gave the flux reversal "Push- pull" current in 
primary!   Makes no  difference as to which pole leads, evidenced by the 
6 cylinder Mercury outboards which were direct drive with no reverse 
gear! It had a "double bendix" starter which when you pulled throttle 
into "Beta" (reverse) and hit start button, engine would start in 
reverse rotation. Magneto was retarded into "After dead center" to fire 
in reverse rotation. "simple"!
