[Mk2] [Turbo] Rev 3 Speedo help

Post by NORRISMR2 »

My speedo doesnt work and cannt figure out why, ive done following...

1.) Replaced the whole gearbox speed sensor with a 2nd hand unit
2.) Rewired the loom at back with new adaptor to gearbox sensor
3.) I put positive end of volt meter to speed signal wire(purple with silver trace wire) at back of clocks and negative to earth and got a small signal on meter...

What is wrong with my speedo they dont work?

The needle was intermit would fly up and down fill the clock etc when i give a bit of the right foot...

Any ideas...

Is yours a turbo? If yes are you using a delimeter chip either at the gearbox end or on the back of the clocks? I've heard these can cause the speedo needle to bounce up and down. If you've got one installed and it was playing up before it might have totally failed now.
