Thanks, ...and any advice(where to find) about wiring diagram for R 20?
...and what about lightening of speedometer R20 ? Was it part of electro instalation or not?

Taz

Sorry, I haven't any direct answers to those...there is a source in Germany (currently sold out, but there's hope, I guess): https://emw-oldtimer.de/Kabelbaum-ohne-Bremslicht-mit-Schaltplan-fuer-BMW-R20-R23 where you can get the wiring harness incl. the diagram...this should answer the speedo light question as well.

@Borgward kannst Du evtl helfen?

If you join the Veteran BMW Owners of America (£30 per annum digital membership from July 1st) they have an excellent library on line and a great archive of magazines.

sorry - I'm just on a windsurfing vacation ...

have a look at the R23 handbook - there you can find a wiring diagram which is also valid for the R20



good luck

correction: the wiring diagram can be found in the document


as far as I remember (I'm about 4000km away from my R23) there is no special light bulb for the speedo - it is lightened indirectely by the parking light bulb

cheers Hubi

i don'T know exactly the R 20-----but for the most prerwar machines there is only a cut - off in the refelector which illuminates indirektly the odometer ( which has a cut off too)

Borgward

yep, that's the way it is 8)
