Ah, the coil wire isn't that bad. Neither is house current. Car
batteries *hurt*. Telephone juice "jangles" your nerves. Electric
catfish make your whole body spasm. Anyway...

As I said, been doing it for years after oil changes, no observed
problems. Think about it - it's the equivalent of really bad spark plug

Yup. My Crown DC300 sits all day with no load waiting for a speaker to
test. No problem. That comparison is part of why I would leave the
coil wire dangling rather than short it.
But, a much better way to deal with this issue is to disconnect the coil
+12 wire, or put a switch in it. No juicy to coil, no problem.
