Alpina brake light

Recommended Posts

I’ve found a couple of old threads on wiring but they don’t fully address my problem...

I have an Alpina 213 but the brake and tail lights aren’t working. The bike has been retired (badly) at some point and the resistor is now missing, and they are apparently unobtainable, it also has a brake light switch with normally closed contacts.

I’ve had one suggestion which is to fit an LED bulb as they’re more tolerant of fluctuations in voltage, though that would need a normally open brake light switch. I know these are available but I’d like to keep to the original style and position, and am yet to find one suitable.

Does anyone have any suggestions as to how to overcome this, or a source of the parts needed?

Seeing as you are already in Europe have a look at Frankie Mountain Spares. He is expensive but I think I can remember seeing all the later Bultaco brake light stuff on his website. Graham.

Thanks, I hadn’t looked there, as you say he is eye wateringly expensive, but may be my only option

I might have a spare resistor from an Alpina. I will have to have a look but if you are stuck let me know and i will dig it out.

I don’t mind what it looks like!

If you fit the brake light the original way, remember that is the Green cable that goes to the resistor and the brake filament of the light. 

The green cable comes from the spark coil not the lamps coil, surprisingly, is like if the bike was having 3 coils, this way there is more power available for the electrical system. 

A Diagram to help to understand the connections is of great help.

The Diagram shows the brake pedal being pushed, so your sensor is the correct one. 

Excuse my English as I am Spanish
