Hi Everybody,
I have a very early K100, sn4196. I've owned the bike for 6 years and it is completely stock.
The brake light has stopped working. It is a separate bulb, single filament.
The bulb is good, tested on a battery.
There is about 6v at the socket constantly, which goes to 12v when the brake lever is squeezed.
The foot brake switch doesn't do anything.
The console isn't original and the bulb monitoring light is not on ever, even when starting. The neutral light and gear indicator has never worked. The console has the pinstripes which appeared about 1986.
I have thoroughly cleaned the contacts at the socket with sandpaper.
So, I don't get how there can be voltage but the bulb doesn't light.
Thanks for any insight because I'm stumped.
Jan
