Hi all, I found this thing.. see pictures
https://www.dropbox.com/sh/sxd1cq8qb...LzNAK-Vaa?dl=0
In the back of a drawer at my house. The previous owner was a pack
rat,
who also worked for the phone company.
It looks like some high voltage flashlight.
What sort of voltage do I apply to the leads?
Thanks,
George H.
As per Boris - yes, it could be a timing light - but definitely a
stop-action device of some sort. I expect that there were other parts
associated with it - strobe-type timing lights have an induction
trigger
device, usually, as one example. + & -attached to the battery, and the
inductor clamped to #1 cylinder spark-plug wire.

But there is no trigger electrode. It might be Neon. Can you hit it
with
some high voltage, maybe from a lawn mower spark plug? See what the
discharge spectrum looks like.
Hmm OK, I could try that.
I'm a little leery of mixing electronics with my lawn mower.
Way back when, a motor wouldn't start, and I convinced myself
it was a spark problem. I couldn't see a spark
after all. I wanted to see how much voltage I was getting so
I hooked up my DMM (though a series resistor), Pulled the
cord to turn over the engine, and promptly blew up my DMM. :^(

Tom, Sorry I chickened out and didn't put it across any
of my working motors. (The last thing I want is to
blow out the spark drive... I'm not really sure, what I'm saying.
Is it ok to put a dead short across my briggs and stratton?
George H.
Doesn't the spark plug do just that when it fires?
Yeah, I didn't say my fear was rational.
I had a bunch of old engines, I think most were "re-cycled" this
past summer.
Hmm, OK I'll hook it up to my old tractor.
(Ferguson to-20) If I blow out the coil it's easy to
put in a new one.
What damages magneto ignition systems is open circuit, wire off plug events.
Then the coil arcs internally.
Don't you have any kind of transformer that could make a HV spark with say a
9 volt battery? A filament transformer maybe?
9V battery and transformer? (how does that work?)
I've got a 120-24 (6A) tranny, how much voltage would you guess I'll need?
I could run that backwards from a Variac.
