Erratic Tach and/or Speedometer INOP

[Mrelcocko]

So here’s a write up about inop jumpy tach and inop speedometer. Remove the 2 screws in pic 1 pull out cluster bezel. Remove 4 cluster screws to remove cluster from vehicle(not pictured)and disconnect 3 connectors plus one small connector for the door chime. Release tabs on top and bottom of cluster to remove clear plastic cover of cluster and bezel as one piece. Next remove 4 screws for Tach and 4 screws for speedometer to remove them. Be careful not to touch your fuel gauge it will not go back to the original location if accidentally touched and moved. Once you have both gauges removed use soldering iron to heat up and melt solder to fix any cracks that may have formed over the past 2 decades. I’ve circled in the pictures marked (speedo-tach)the 12 soldering points on each gauge to reheat. This fix will only work for 96-97 R50s. This is a guaranteed fix for the gauges as I have done 3 now and all three I’ve done this procedure and the problem was gone after completion.

Update on both Speedometer and Tachometer. Working like a charm. This is definitely the fix
