2001 yamaha gp800r multifuntion display not working

[blackthunda77]

i went out to the beach yesterday and halfway through the day the multifuntion display went out on me. no rpm, no speedo, no gas or oil levels, nothing. it doesnt even beep anymore when i start it up. everything else works fine. was alil wet inside from all the splashing and some of the wires were wet but i though those things r supposed to be water tight? i disconnected all the wires conected to the display and hooked em back up today after drying them out and nothing, same problem. anyone know of something i can do or do thses displys tend to die off. ski only has 45 hrs on it though. i tried to take the display off but cant to the hell of me find out how to take that sucker off. can anyone help me out?

sounds like a ground wire went bad look for a black wire in the harness and put a jumper to the neg side of the battery and see if they come back on

where would i hook up the wire on the harness side? just splice it into the black wire anywhere?

I use a pin probe and slide it in the wire to make a conection then clip it to the battery ground lug. put a drop of superglue over the hole in the coating to seal it if it is not the problem so moisture won't get in where you made the hole, then try another one

check all fuses also, I believe a relay turns on the power to the info ctr if you can find a diagram see if there is a relay involved .

wow, i cant believe i am bringing up this thread back from 5 years. Display is still not working (or so i think). While de winterizing the ski this year my fiance said, hey i think i saw the display working. Didnt pay much mind to her, but while testing the ski i too noticed the display VERY FAINTLY seems to be blinking on a off. You really cant even notice it unless the sun is beating right on it. Any input to that?? I tried to do the ground testing, but maybe i should try again, in more locations?
