You are among about three people I have ever met who understands the way the system works. Keep up the good work.

Gene,
Thanks for the second reply! On the other ones first let me say this. I work in a nuclear pharmacy maintaining a particle accelerator where we make radioactive isotopes. I get asked what I think are stupid questions ALL the time. Do you glow is one of my favorites and they are serious. When a new employee comes in they are always overwhelmed with the job. To me itís easy because I do it everyday. I donít have an electronics degree but I wish I did. When I ask questions itís to learn, Iím not sending my car to a mechanic when I can LEARN how to do a job.
On the electrical side of this for most people that are not in the know. When someone says check how many amps it is pulling they may have no idea what an amp is. The same as if I was trying to tell someone how to adjust the beam strike on the target of a cyclotron. (well you just move the collimator up or down a mm or two) That is easy for me. Did you or anyone else understand thatÖNOPE! You would need more information like where is a collimator. To me that would be a stupid question. What I am trying to say is give us electron challenged people some slack.

weak spark voltage? What do I win?

I thought the capacitor/condensor was there for 2 reasons, one: to reduce corrosion of contact points and two: to give the contacts a cleaner "break" (absorb current spikes)

Coils with a R of 1,5 Ohms? Some are as low as 0.5 and others are up to what 2 Ohms?? maybe higher? I think your 1,5 only roughly applies to points.. and who but bird uses points these days

Believe me when I say these guys were not addressing you. It is the guys that argue that we are wrong.

Yes. I am talking points.

The condensor does do 2 jobs: Protecting the points contact from burning and it maked the mag field of the coil collapse faster producing maximum spark for that coil.

Yeh, not directed at anyone here, but sometimes I get tired of guys too lazy to go look up a elementary electrical book in the library even....

or Radio Shack, or maybe even the NET, for free, but all it seems is to be a short explanation with more questions unanswered, or some one selling information.....

After being in electronics for so many decades, and remembering vacuum tubes, much less morse code from ham radio daze, it's all a natural....so it feels like I can visualize an electron stream, and magnetic fields, and
the measured affects on instrumentation....used to be a design ET, working for engineers who knew much more than I did....PHD in EE, and PHD in Nuclear/Physics.....PHD in Chemistry, MS in Mech E.....

I just set down and listened unless quipping a joke.....
