I need some help. I’m building up a 1979 xl 185s and I can´t get the electric to work, I have no wiring on the bike, I have to wire it completely new. I have temporarily wired it to see how it works the front light goes on but not very bright at all, the horn I can feel vibrates a little but no sound. I need front-, backlight, turn signals and horn. I do not want to use a battery. The alternator has 4 wires. Can somebody tell me how to hock this up and what I need? Regulator or whatever? Sorry about my English.
