Re: Weather/coil performance
Original poster: "Barton B. Anderson" <bartb@xxxxxxxxxxxxxxxx>
Temp and humidity can cause a change in resonance, but not to such a
drastic degree (in my experience). Because you retuned and found
resonance near where you started, the cap is likely ok. Diminishing
sparks as you described would point me towards the transformer. Check
to make sure it didn't die. It sounds very familiar to an NST that
shorted one of it's hv windings. Could have happened right when you
turned off the coil before the weather change.

How do different types of weather effect coil performance? I ask
because my coil was working fine last week when it was around 75
degrees. But the temp has now dropped to a nice normal 30.
I can get the spark size that the coil produced but only when the
spark is going into a grounded object. As opposed to the operation
last week when it would just discharge into the air. Not even a
small spark into the air.
I am guessing the problem is either the temp or humidity because
nothing else has changed since I last used it. Just been sitting on
the table. I tried re-tuning it to see if that would help but it
tuned at just about the same tap point. So i don't know.
