A good coil will produce a spark up to 1/2" long. A simple test when it 
is in the car is to pull out the centre lead from the disturber and 
either lodge the end so that it is about 3/8" away from the engine. The 
water tap body might be the most convenient. Then turn on the ignition 
and press the starter using the solenoid button if necessary. The 
alternative is to hold the insulated section of the HT coil lead away 
from the engine but for this I would recommend wearing rubber gloves.

In my case of loss of coil oil and overheating, I had lost almost all of 
the spark when my engine failed. It had a job to produce a spark more 
that 1/8".

Interestingly when everything had cooled down the full length spark 
returned. So in theory I could have driven another 1/4 mile or so before 
misfiring and subsequent failure.

Regards
