Title: Lucas k2f spark pictures
Post by: a10gf on 07.08. 2009 00:15
My k2f with an old plug. This is what powers our bikes!

See the blueish flat 'cloud' that always appear? It forms on the inner electrode on one mag firing side, and outer electrode on the other side, probably sign of an inverting L\R polarity of the ht supplied by the mag.

As an anecdote, my canon slr went nuts when held close to the running magneto, locking up with all kinds of error messages onscreen. And surely, I am too close to the mag as well...  ;)

wow, that is very nice photography! 

interesting that it interferes with the camera! do you think it is the magnet, or the electrical field?

thanks for sharing!  *smile*

Thanks, that was quite difficult to catch 'on film'.

Looks like any electronic stuff got problems very close to the mag at high speed, even my laptop locking up, with display flashing on and off.

For some really unique sparks, swap the Lucas for a Tesla k2f *eek*
