Jack,

Model "T" coils run on 6V at idle, but a "T" magneto puts out 30 
volts or so at higher RPMs.  So if you are running a "T" coil for 
Tesla purposes, don't hesitate to push it harder.

Not exactly sure what a Jefferson coil is, so maybe my advice isn't applicable.

Is there any chance you could post a copy of the article/plan for 
this coil?  Sounds like fun, and would be a fun project for a "T" 
owner like myself.

Thanks,

Curt.

Hi Curt (great looking car!), Ed (I'll describe) and all,

Having never worked with a Model-T or small gas engine coil, I am
embarrassed to say that I thought with six volts applied, the
vibrator would work, yield a spark and I would be on with the TC coil
project. Advice from a friend (Frank) quickly let me to take the
contacts apart, soak all the pitted pieces in water bleach and polish
and reset the gap. Doing that now. No tar leaking, this is a
Jefferson coil rather than a Model-T coil.

Thanks for the tips on the tar, capacitor and possible burned-out
secondary. That will be next if the clean up and reassembly does not work.

If anyone knows a lead to vintage spark gaps (such as the California
Scientific or the Mesco Zinc gaps made around 1915, please let me know.

Best,

Jack

If you want to remove all of the tar --put it in an oven (in the
garage) in an old baking pan. Space the coil up from the bottom with
wood blocks. TJ


Sounds like some work. I'll try cleaning up all contacts and points.
The secondary (so I have read) often burns out on these old coils.

Your help and fast responses are appreciated!

Hi


     PRIMARY can burn out if contacts stick shut (maybe if capacitor
shorts although I've never seen that happen.  Usual symptom is that
the case is oozing tar.  You still haven't described the problem
(unless I've missed it).
