2003 R6 tach & digital dash not working need help troubleshooting

[RedlineBandit]

I'm having trouble with my 2003 R6. The tach and digital dash aren't working, but the neutral light and turn signals are good. I found two unplugged wires under the rear seat, but I don't know if that's the problem. I've looked for other loose connections too, but didn't find anything. Has anyone dealt with this before or have any ideas?

The unplugged wires might not be related but best verify with a wiring diagram. Likely a power or ground issue causing the tach and dash to malfunction

It could be the dash power or signal feed getting cut off. Try plugging those back in carefully and see if that wakes up the tachometer and dash.

hmmm, it's weird that the neutral and turn signals are fine, but the main display is out. That immediately makes me think power/ground to the dash unit itself, or maybe a main data signal wire

Could be a blown fuse, check the main fuse and all wiring to the cluster, especially around the front fairing.

My take is ground issue to the dash cluster. Since your neutral light and signals work, some circuits are getting power, but the dash might be missing a key connection.

If it's not the fuse, then it's probably some wire related issue, like the other said. A multimeter can give you all the answer you need, but you'll need to find a diagram first to know which wires to test.
