why does the tail light quit working when the turn signal stops working?

Curious if the original poster ever located his problem....?

Hey Stan,
On my R80/7 the turn signals and break light did not work at all.This happened all of a sudden.First thing I checked was the fuse in the headlight bucket.It was loose.I tightened up the connections and signals and break light function.

Ebay has nice diagrams.

Type in BMW , model#, wiring diagram on Ebay. There is someone out of New England selling large colored laminated ones for $17.00. I bought one and keep it rolled up and onboard along with back probing connectors, an oscilloscope, frequency analyzer, current probe, and timing light.......OK, just joking about the timing light.

Try Ebay.

I had a similar problem on my 1982 R100RT. The connection for the various rear fender lights sits above the battery, and unsurprisingly was very corroded. Cleaned that up, problem solved.
