The instrument cluster on my k6 750 is working only spasmodically. It seems to work OK for a while after the battery is disconnected and then reconnected, then dies overnight. Almost like a boot up problem. The red backlight is working but no LCD. Is the cluster broken or is there another fix? Thanks in advance.

Stator or rectifier might be about to take a shit. Usually the tell tell sign you are about to have issues. Just a possibility

If the tachometer and various indicator lights are working properly and assuming the engine starts and runs properly, it would seem that the cluster has failed internally.

Keep it simple. Anything else in the front end acting funny? A bad connection between the main harness and front subharness is known to cause problems like this.
