[AT] No spark

[Matthew]

Take a 12V bug light and put it across the coil's low voltage terminals and
try cranking the engine.  The light should flicker on and off as the points
open and close.  If that happens, then the problem is on the high voltage
side.  If that does not happen, then the problem is on the low voltage side.

Put a neon lamp from the hight voltage contact on the coil to ground and try
turning it over.  The neon lamp should flash brightly.  If it does not you
have a bad coil.

Next, re-connect the center wire to the distributer to the coil and try your
neon light on each of the spark plug holes on the distributer.  Turn it over
and you should get bright flashes, but less often (1/4 or 1/2 to be exact)
If that is the case you got bad wires or plugs or something not seated right.
If that fails, something in the top of the distributer or roter  is messed
up.  The contacts on top of the distributer should be checked and the contct
on the rotor.

It is not black magic, just a matter of figuring out where it is broken.
