Having the same issue with my '90 740 GLE. That and an ABS light on.

So far I have pulled the cluster, reconnecting all the contacts with dielectric lube. I then cleaned all the ground points under the hood, ceptin the main one that runs under the motor. Still gotta do that.

It was bouncing all over. Now it has settled to pretty not working, period ...but will bounce up a bit when I hit a good bump. Makes me wonder if there is an issue with the connection on the rear end. On my list to check.



There is a good bit on this issue in 700/900 FAQ.
http a://www.brickboard.com/FAQ/700-900/ElectricalInstruments.htm

Hopefully some new ideas and help coming for both of us.
