instrument panel gremlin

I have a 2001 rc51 bought it 2 seasons ago wrecked(mostly cosmetic) put new plastics and misc. pref. mods.(pc3 etc) its been fine other than a loose ecu connection that seems remedied with dielectric grease and zip ties. late last season, mid-ride, the instruments all went blank and stayed that way until I applied the brakes(either front or back) then it came back on until I released the lever or switch,then it will go blank again. the bike runs fine otherwise. has anyone ever heard of such a problem? i'm not sure how to troubleshoot this. thanks derek

^+1 The ol loose ground has found it way to you it sounds likege. t a fresh tube of dielectric and a small box of q-tips and check those connections.

Without being exact, feedback. Closing the brake circuit can get you the ground needed for the display circuit.

Do you have a manual? You can download a freebie here.

I do have a manual on CD, do you think a particular ground might be found on the wiring diagram?

Just check the continuity of all the grounds show for the instrument cluster, and see which is open circuit.
