Petronix Electronic Ignition Any Good?

I just had a thought, could a very long coil to dist wire be to long [ my is 24" long], coil mounted on the inner fender well? 318 engine, Have weak spark as shown with a spark plug test light. Car seems like wants to start, have a few hits but will not run. Tried to see if by turning dist. to adjust timing would help but no change as to how the car tries to start , I have the coil wired as per the instructions, that is - and positive wire hook up. Power from ignition switch to + on coil, and red wire from Pertronix dist, and black wire from dist to - on coil.

An overly long coil secondary wire can cause stuff like RFI/ EMI / radio interference, but unless the wire is actually defective, that length should fire OK. Check the resistance with your ohmeter

Then put your meter on coil+ or if you have a ballast, connect to "key side" of ballast, and ground and measure voltage first with key in "run", with engine stopped, then again while cranking

You should have close to 12 or more "key on" (with no ballast) and at least 10.5 or more when cranking.
