What do you think can cause coil failure, besides simple deterioration from
age and heat?
  Is it a bad thing to short the HV coil wire to ground while doing a
compression test?
Would continuous current thru the primary side cause overheating and damage?

When I find old coils lying around in vans that I have bought for parts, I
get the feeling that people have changed them attempting to fix other
problems.
