Mediamab Posted May 18 Share Posted May 18 So… finally got around to replacing ignition system last week was running beautifully and in perfect time. Engine suddenly cut out today (luckily on driveway) and now won’t start as no spark… have checked coil is getting power all fine and there’s power going through the lead into the dizzy. Rotor arm is moving as engine cranks over. Have triple checked all wiring (replaced most) and am 100% all wires are where they should be. swapped back to the old coil and made no difference either. any ideas as to what could be happening?!

Mediamab Posted May 18 Author Share Posted May 18 And just to confirm I have the red wire from the dizzy going to positive on coil. White wire going to negative. Green wire going to positive from ignition. Quote Link to comment Share on other sites More sharing options...
mad_pete Posted May 18 Share Posted May 18 Isn’t there another wire coming of the dizzy for something ? My connector on there perished and I lost power because of it but it was a while ago. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted May 18 Share Posted May 18 Points, electronic ignition or RRC style amplifier? Quote Link to comment Share on other sites More sharing options...

My connector on there perished and I lost power because of it but it was a while ago. There is an earth point as well which it says isn’t a necessity. Didn’t have it connected when was working fine. Did run a lead from it just incase but made no difference Quote Link to comment Share on other sites More sharing options...
Mediamab Posted May 18 Author Share Posted May 18 I assume if there’s voltage to coil with ignition on then there would also be voltage when cranking or could I be onto something there? (Still learning so appreciate if that’s a dumb question!)🤣 Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted May 18 Share Posted May 18 Well, there *should* be... Quote Link to comment Share on other sites More sharing options...

Just seems strange suddenly cut out and now won’t start but was absolutely fine! Quote Link to comment Share on other sites More sharing options...
Mediamab Posted May 18 Author Share Posted May 18 Could it be the amplifier? Though struggling to find out how I’d test that? Quote Link to comment Share on other sites More sharing options...

Mediamab Posted May 25 Author Share Posted May 25 Ok put old dizzy back with the new plugs and leads and works a dream, so can only assume something failed but least it’s working again ha 2 Quote Link to comment Share on other sites More sharing options...
