mick annick Report post Posted May 4, 2020 (edited) 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? Edited May 4, 2020 by mick annick Quote Share this post Link to post Share on other sites
bullylover Report post Posted May 4, 2020 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. Quote Share this post Link to post Share on other sites
mick annick Report post Posted May 4, 2020 Graham Thanks, I hadn’t looked there, as you say he is eye wateringly expensive, but may be my only option 1 Quote Share this post Link to post Share on other sites
petorius Report post Posted May 4, 2020 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. Quote Share this post Link to post Share on other sites
mick annick Report post Posted May 4, 2020 Ooh, yes please, I’d love to keep it original Quote Share this post Link to post Share on other sites
petorius Report post Posted May 5, 2020 Just dug it out, it does have a rustic look. Quote Share this post Link to post Share on other sites

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. Quote Share this post Link to post Share on other sites

Antonio Report post Posted May 19, 2020 The Diagram shows the brake pedal being pushed, so your sensor is the correct one. Excuse my English as I am Spanish Regards Quote Share this post Link to post Share on other sites
