BMW 50/2 Dimmer switch wiring questions
I am attempting to install a new switch on my 67 BMW R50/2. Although I thought I replicated the old wiring positions somehow I didn't and light is not working. I looked at the wiring schematic for this bike and the wires are not same as listed. I am hoping that someone will be able to help me match the correct wires to the correct terminals.
Colors listed GE( Geld ) Yellow, WS ( Wiese ) White, GN ( Green) GE-WE ( Green/White). Wire colors on bike. Black, Brown , Blue, Blue Green.
thanks

The headlight works when running or not running
Headlight should go on as long as you have a good battery, key is down and turned clockwise

Re: BMW 50/2 Dimmer switch wiring questions
As Tommy/Chris/Kurt are saying the magneto energizes the sparkplugs, period.
The generator energizes the battery.
The battery energizes the lights.
When the battery is crap, the generator energizes the lights directly, and if not turning at sufficient rpm, the generator will not produce enough energy, and the lights will dim or go out.

Re: BMW 50/2 Dimmer switch wiring questions
I checked voltage ( with key off !? ) and get 6v at all terminals but light is not on. I can understand that the wires are shorting out in the harness but I don't understand why my light is not on?
thanks
