Re: [TCML] Bleeder for a Pulse Cap - how to?

[Gary Lau <glau1024@xxxxxxxxx>]

Cause "stuff" happens.

I once had the brilliant idea to determine the optimum primary tap by
dragging the primary tap connection across the primary turns (with a long
insulated stick), while the coil was running, to see which gave the best
sparks.  The arcing between the tap connection was fearsome and I
immediately abandoned this foolish idea.

I shut off the power and picked up the tap wire to  attach it back to the
primary.  ZAP!!!  Luckily the remaining charge on the cap was not serious,
but it easily could have been.  So, by removing the tap connection, the
normal discharge path through the NST was lost.  One could come up with any
number of alternate failure modes that would achieve the same thing, and a
bleeder would correct any of them.  Of course the bleeder connection could
also fail, but just do what you can to stay alive.
