Who can help a Luddite with Honda Wiring?

Can anybody guide through the haze on this goofy honda. I believe it's a 1978 Twinstar 185. I have a new battery in it (6V). I have absolutely nothing working. If I jump over the lugs with a screwdriver on the solenoid the starter rolls, but that's it. No lights, no horn, no turn signal, no ignition. Is there a master fuse in here I'm not finding? Last year I took apart all the conections I could find to clean and reassemble. No change. My neighbor wants his bike back that I told him I would fix two years ago.... ;^}
