[SEL] Generator / Magneto

[Luke Tonneberger]

Hi Guys,

I should have changed the subject, but I kept forgetting, sorry.  John 
Cullom sent me a scan out of a catalog and it shows an item similar to the 
one Steve pictured and it is called a magneto. It shows the coil inside the 
magnets. It also says on engines of larger horsepower (with larger 
flywheels) enough speed cannot be obtained to properly fire the engine when 
starting. So it is started on battery and coil first then switched over to 
the magneto. This is the purpose of having the coil inside the magnets.  
Still thought a coil should be kept away from a mag, but maybe I was 
mistaken??  The scan John sent talks about three mags. Two of them are the 
type I'm talking about and what Steve showed (for a make and break system). 
One with the coil in it and one without. The third one mentioned is for a 
jump spark system, which sounds like the system Dave has on his Domestic. 
Could someone maybe explain the difference between the friction drive 
magnetos for the make and break and jump spark systems?
