I'm well aware of that. But I thought I'd mention it.
There's a wire diagram around here somewhere if you'd really like to check it out in depth.
The part that confuses me is the quasi-conection between the two semi-separate halves of the magnito.
The headlight only works when the engine runs. It works with the battery connected or with the wires disconnected (but dimmer.)
The horn only works when the battery is connected, but it gets a little power if it isnt.
The back brake light and the horn both come on with the key if the battery is connected.
if the engine is at a very low idle, the headlight is on full, the tail light is on full, the turn signals are on and you hit the horn, the engine will idle lower or even die.
All this and more that I cant even remember, as I havent seen my bike in 2 years.
