Relatives of the experimenter formerly known as Joe

I've had very few belts but the one I remember from a spark plug
was very much like getting your fingers bashed with a mallet, so I
will be trying very hard not to get zapped

The message coming through is that the insulation and relative
voltage is what needs to be considered.

I'll have a think about Dwayne's phase idea. The secondary terminals
won't be 0V referenced, as they could be in a car. This particular
ignition coil is recommended as it's intended to supply two spark plugs
in series (hence the 30,000V), which implies that at least one terminal
of each spark plug is isolated from the block

A safety gap sounds like the best plan to give the coil a discharge
path if the main 'load' isn't there. I had thought about a resistor but
that's a constant parallel load and I've seen the state that a TV focus
resistor gets into. One I replaced was ISTR a 22M 5W. The faulty
resistor was very much the worse for wear

The experiment I'm thinking of probably might use an EHT neon
transformer, as that's the only simple available thing I could think
of when I first saw it that would be available OTS with that much
*relatively non-lethal* voltage
