@DoveG where in Scotland are you? I'm in Forfar, 15 miles north of Dundee. Here's a wiring diagram that might be of use to you. I also suggest this wiring mod, fitting a relay to power the ignition directly so that the supply doesn't need to go through the ignition switch, kill switch and all the many connectors in-between.
Thanks for that Derek, I live near Haddington just a couple of miles from East Fortune racetrack. Any electrical advice is greatly appreciated as I admit to having very average skills in that department.
Hi DoveG If you're still stuck with the electricals, then Tyler at North Edinburgh Motorcycle will certainly be able to help. He's a Ducati specialist and at 22 Manderson St, Edinburgh, EH6 8LY. Tel 07711 937019. All the best. 2Twins
