Spark colour

[mickm]

I’m having problems trying to start my Classic. It’s been dormant over the winter. It rode into the garage,but will not restart. I’ve replaced the plugs,leads, and plugcaps. I was getting a green led on pressing the button, with a red flashing on cranking. After cleaning all the connections I now get no green led, a flashing red, and a white/red spark. I’ve cleaned earths from battery and alternator. Have two batteries so no voltage drop, but still no joy. I’m at the point of sending the unit to Graham for testing. Before I do this has anyone got any ideas that may help.

Hi, is the bike firing at all?
If not I guess the bike must smell of petrol?
Just checking

Hi Roy. It’s not firing at all. Plenty of vapour comming out when looking for a spark.i was wondering if the relay has dirty terminals would that give a lower voltage/ amps to the coils that producing a poor spark? So new relay on the way! How many earth points are on the bike any ideas ? That’s another thing to check. So off to the garage again.
