My indicators stopped working so I decided to clean the switch (Sparx version of Lucas 187SA), it seemed such a good idea at the time. Stripping was no issue, but... the little copper "u" shaped bit went flying on re-assembly. I cannibalised an old torch & created a replacement, and then promptly lost the spring 7 found it & lost the copper bit & found it & lost the spring (repeat for 3 hours or so); I gave up after losing the spring one last time.
I returned to the problem last night & managed to re-assemble using a cut downspring from a retractablebiro. Fantastic - it worked.
Re-assembled & it no longer works, not sure if the spring is too weak, or too strong or maybe the copper bit is a fraction too small. Ironically I also have the original Luscas switch, that is also missing the indicator spring & copper "u" (that's why the Sparx unit was purchased!).
Any further ideas are welcome! I am reluctant to replace theswitch cluster asthiswould also involve replacing the clutch lever & mirror mounting.
Cheers, Mike

Can't help on the parts front as I don't have a MK3, but if you need to work on another switch do it inside a clear plastic bag so any flying parts stay inside the bag.
