Skyline R34 Gtt Speedo Playing Up!

[Charlie Bun]

Hi all,

I have an R34 GT-T, and the speedo/dashboard panel has been playing up. When I switch to accessary mode, it goes fully retarded (refer to picture below). When I am driving the speedo and rev meter max out and than everything on the pannel (speed, rpm, fuel, temp and odo) all go to zero (odo goes blank). After about 5 min the fule and temp usually come on first and than a few sec later the speedo and rpm will come back. When they come back they are way out. I will be doing 60 and the speedo says 120. If i keep driving it will max out again and repeat what i said eairler.

When I have a chance I will upload videos and put links for you to see.

Anyone have any idea what it is and how to fix this issue?

I have seen topics about this around but there was now real solution.

Your help is much appreciated.

Thanks.
