07 GSXR600 Speedometer Problem : Suzuki GSX-R Motorcycle Forums: Gixxer.com

Hey guys I'm having a little problem. I bought an 2007 GSXR 600 with the speedometer not working, it lights up, all of the lighted icons work but the rpms needle will not move, and anything digital is blank. So I said ok ill just buy another speedometer. After riding with it for a couple weeks the new one came. I installed it with no trouble but there is no change, this speedometer is doing the same thing. I'm starting to think I have a bigger problem but besides it being electrical, I have no idea what it would be. Any thoughts or ideas on what it is/what I need to do to fix it?

I'm assuming the plug in the back of the display is plugged in all the way and is not damaged.

Check the big plug covered by a white/clear rubber cover just forward and left of the display. The display wiring runs through this plug also.

There is a wiring diagram in the back of the service manual. I could be very helpful tracking this down.

I took a look at the diagram and found where the harness was so I took off the fairings. I noticed as disconnected the plug that there was a connection missing. Only one, but I'm not sure if that's enough to cause the problem. Nothings corroded or broken, that's the only thing out of place.

Compare the diagram with the wires in the plug by color code and figure out which one is missing? I think the O/G is power in, but not 100% sure.

I have the same issue but nothing missing..

Yeah I'm not sure if that's a big deal or not but I ohmed out every wire in the front harness and got little to no charge so I'm thinking its either that wire harness or maybe the speed sensor killed everything? I'm running out of things to try

Edit Never mind

Do you know anyone close by that has an 06-07 gsxr 600/750 that would try your display on their bike? I know it would be highly unlikely to have two bad the same way but not impossible.

Ohmed out but no charge? I have no idea what this means.

The speed sensor will not kill anything. I will just read 0.

I have a friend with a working one, so will see whats up.

Not that I know of, I wish I did. Yes that's what I thought the speed sensor wouldn't affect the digital readout. Maybe a new wire harness for that side?
