So let's get down to something basic here: ya gotta take a plug out, hook it to it's wire and lay it on the block or
manifold or something. Rig up a little jumper and crank the engine over and simply look at the quality of spark you see. If you can do it inside a garage with little light, all the better.
The spark should be nice and fat and you might even hear it. This is what you paid money to Pertronix for.
More fundamentally this is what any of us needs to be willing and able to do in the event the ol' car does not run. The car needs 3 things: compression, gas and spark. TBird, Ferrari or lawn mower. Do you have all 3?
