Congrats vapemonkey on getting a working genesis its a nice feeling.
And not to pick fault, especially if it works but was there a reason for picking those places for the negative and positive ends of the coil? I would possibly have used the hole in the bottom of the neg terminal or moved the whole thing round to the other side and started the bottom of the coil using the large screw. Also you are missing the top terminal nut which would have meant you could have spread the coil. Your arrangement looks to be strangling the coil.
All that said, if it ain't broke........break it?
