Grounding Question

After being upside down for about 2 hours, i was finally able to find... and remove the grounds for my instrument cluster. I cleaned them up, and reconnected them. But my fuel gauge needle is still bouncing when i hit the brake pedal. Anyone have any thoughts?

I have this same freak needle jumps. I think it's some kind of positive drain. The instrument cluster is old. Nothing can be done.
