My tachometer, I think, is goosed.
A healthy slap on the dash with the engine off will return the needle to 0. However, as soon as I start the car it will flip up to 2600 and stay there - even with the engine off.
I've checked the wiring, got continuity... my guess is the actual clock is somehow broken internally, so I'm after a new one.

It's a '91 SE turbo with a boost gauge built into the same clock, so ideally I'd want to replace like-for-like
