Ruby's electric problems

[Denis Sweeney]

Thanks John and Bob for all your comments and advice, far too long a story to bore you all with but Ruby is back up and running again, the cause of the problem was as you both correctly predicted, a failed earth connection.
Briefly, where I had added the suppressor at the earth point next to the coil, my poor crimping of the connector had failed and so lost the earth connection which then caused all the other issues.

A lesson learned.

Cheers and thanks again
