Hi Earl, welcome to the forum. Mayo is a beautiful part of the world. Sorry to hear about the storm damage - we had lots of trees down during Eoywn but I believe Ireland had a lot worse.
In my limited experience there is no real substitute for understanding your bike's wiring. With no light checker etc there is a lot less there. Think of the electrics as a number of systems - charging, five wires from the alternator to the regulator and rectifier to the battery. Then you have battery to fuse box to ignition switch, then the ignition system - coil(s) and Pamco. Lights, brake lights, horn. With no flasher, that's just about it?
Could take the seat and tank off and drape the harness over the bike and start thinking about what needs to connect to each component. Even if Heiden's diagram is a bit vague, it should provide some guidance?
Photos always help, so when you get stuck, not that you will, put up photos of the relevant area and suggestions will be forthcoming. Cheers, Raymond
