I've had an aftermarket rev counter in my mk1 Mini for ages and it was fine until recently, then needle started bouncing around between zero and 1500, whatever the revs. Fine - I replaced it with a fleabay special which wouldn't react to revs properly and was wildly innacurate, so that went back and I bought a more expensive replacement. That was OKish for a week, now goes straight to max when you start up. Could something else be going on, other than a whole bunch of chinese made crap? They are 52mm gauges and take the signal from the -ve terminal of coil (neg earth car)
