You'll need to check the ignition amplifier is working. Also check resistance of pick up in the dizzy and that the air gap is correctly set. If you do a search I seem to think I posted the test procedures not that long ago.

once you have found it put the links up for lazy people like me to find , I wouldnt mind knowing. I normally just test it by swapping it lol

I had broken wires/short circuit at the ignition amp where the insulation had split and was grounding to the braided sheath.

Worth checking!

Otherwise, the ignition system is very simple, if it ain't the plugs, leads, or coil, it's the dizzy or amp, or any of the LT wiring in between it all!

Cheers, sam

Also check you have a good earth. I once had a problem where it was getting enough earth for everything but the coil/amp.

NO spark
