Hi everyone,
Sorry to dig up an old thread but I have the same issue. There's clearly moisture in my display so I am assuming this is most likely to be the problem. My backlight is working in my display but that's all that works. No tach sweep, no lights besides backlight, etc. I did check the red/white wire on the 12 pole connector and it SEEMS to be okay. I did not pull off the sleeve to check it all the way up though.
Is this something that KTM will help replace because the product is not properly designed?
If not, are there any good aftermarket gauges that are compatible with this bike?
