I hope you can help! I have a 1966 BSA A65L 12-volt fitted with Boyer Bransden electronic ignition and dual coil, also modern rectifier and diode all nearly new. The other day the bike would not start. After a lot of kicking I took the tank off and put some ignition testers (red plastic plug-type thing with an LED inside) between the plug cap and plug, kicked it over, and the LEDs did not flash. I took the plugs out, rested them on the cylinder head with the testers, kicked it over and they flashed. I put one plug and tester back in the hole, the other on the cylinder
