Speedo/Tach not working – 2007 Suzuki GSXR 600

The GSXR’s seem to be plagued with speedo problems. On this particular bike, the owner has tried to replace the speed sensor and the speedo cluster. Swapping these components did not resolve the issue.

Here is a pic of the cluster, where the speedo, tach, and fuel light are not functioning:

Armed with the wiring diagram located in the service manual and a multimeter, I had a feeling the problem had to be located in the harness. After removing the fairings, the problem was very apparent. The unsealed connector located on the left side was corroded!

The red/blue wire was hanging on by a strand! I made an attempt to locate the factory plug/receptacle & pins. It was nearly impossible, and I bet the cost would have changed my mind anyway. The wire was repaired using AMP Faston quick connect spade terminals.

Any remaining corrosion was cleaned with CRC Electronic Cleaner. Here is a pic of what a properly functioning speedo cluster looks like:

  1. Thanks for the post I had no idea what was wrong with my gauges until I saw this! When I wiggle the wires near the unsealed connector the gauge turns back on. I am having trouble pulling the harness apart as I don’t want to rip all of the wires out. Is there a latch holding the two together? Thanks in advance!

    • Hi Jeff.

      Yes, there is a latch that holds the connectors together. You can use your fingers or a small screwdriver to release the latch/tab. Looking forward to a functioning display?

  2. I have a 2007 gsxr 600. Everything on gauge works perfect except my rpm. it stays on 0. when u turn on bike it doesn’t sweep& shift light doesn’t light up. could this be my stepped motor?

  3. Hi Matt,

    I’m searching for a wiring diagram of the plug on the instrument panel of a GSX-R ’06. Can you help me out?
