Fuel gauge and trip computer dead - anyone able to help?

Hey people. After re-painting and installing my rear cowl, I started the bike up after many months of just sitting there. I noticed that the LCD screen that serves as the fuel gauge/ trip computer is dead. I looked in the forums and can't find any reference to a common issue, so I am checking to see if anyone has had their on board computer screen die after monkeying with the bodywork. I have had it off multiple times and not run into a problem before. Now, I am concerned I might need to tear the fairings off and get my nose in there.

Thanks all.

What have you checked since this started?

 

My bike has an undertail as well, so everything is moved around. I checked all fuses (main block and a smaller block with just a couple fuses) all connections, confirmed battery voltage is good and checked all other functions. I do have a front brake switch out, but that is confirmed as being the little microswitch. I have a new part for that on the way. The bike starts and shifts fine, neutral light is functional, kickstand kill switch is active.

My R/R is already taken care of with soldered connections. Although when I think hard, I don't recall checking that stator output voltage is good. I'll check that later this week.

I would inspect the big grey and blue connectors for corrosion and heat damage. I would also clean the orange grounding block and any connections you can find leading to the dash. Oh and definitely check your fuses.

 

Hopefully I get some time to open her up this weekend. My clock is still working, it's just the temp/fuel/trip area that is out, so maybe I should pay close attention for corroded connectors. I'll take a good look at the schematic too and see if there is a common power source.

Check the traces and solder joints on the circuit board.

 

Jose,

If you haven't seen it before, there is a colorized he-rez version of the 5 Gen wiring diagram over at VFRD. This should come in real handy for you.

Maybe a silly but often overlooked suggestion: check the fuse. I had a tail light go and it took the instrument panel off line as well. Clock was on, but no fuel, no MPH, no temp.
