Recommended Posts

I've got an intermittent fault with the speedometer in the supe, on tick over it jumps up to 40 mph and then when I excelerate it goes up rapidly and can go up to 180mph and can be all over the place.

 

Its done this the odd time before but now its getting more often, has anyone had this problem before?

 

cheers Ste

I'd hazard a guess and say you have a short circuit somewhere.

Take the clocks out and have a look at the connections then follow the cable back to the fuse box.

I had a boost gauge that used to jump around all over the place, it was caused by rainwater geting to it.

 

Only a guess mind you.
