K100 Speedo ribbon to three pin fixture delaminating...
« on: July 23, 2016, 08:35:45 PM »
Over the years, my speedometer pins have had to be messed with enough that it appears now the ribbon is delaminating.  Again, I had to look at the pins today after intermittent speedo readings started occurring again for the first time in a couple years. This time, I noticed that the ribbon is delaminating, which over time, could spell curtains for the odometer.  I cleaned and tweaked the pins- something I haven't done before, and put a light carbon conducting lube on them and reseated. I also put foam over the pins,but stuck them to the outter case, that when put back on, applies force to the pins.  Maybe this will help the intermittent problem.

As a question- has anyone done a complete ribbon bypass with direct-soldered wires to the speedo as a permanent fix?  It appears that the engineering of the bike will outlast the cluster- my intermittent speedo is looking terminal...  Pun intended...

  It appears to hat the same big erring of the cluster will not out last the bike . . .
I swear that my cluster erring is differently small.

Just got back from a steaming hot, 100 mile ride north of Tampa, at 80+, and the speedo didn't miss a tic from the beginning. I do think my idea of constant pressure against the pins and for about a 1" square area will do wonders....

BMW did have the same idea in -86.......this connection have been modified by BMW several times,
the final mod was a two 4 mm screws.

Is the ribbon cable pictured above with the plastic bracket with provision for two screws available from BMW? I've looked thru the fiche at Max and I'm not sure I see it...
