Rev counter
 

Took the day off yesterday and went for a run to the coast. On the way back the rev counter started to read erratically and eventually stopped. I was passing Ron Parkinson m/c's and stopped to take the cable off and get a new one (I assumed the cable had snapped again). But no, the cable is fine. Put it back and all worked ok for the next few miles.... then stopped working again. Any ideas?:(

Oh yes, its a 1994 600SS

I had a 94 900ss that this happened to. turned out to be one of the drives - but I can't remeber if it was inside the tacho or at the engine end. It was repairable (as opposed to having to be replaced)

You could always buy a second hand tacho, but check that it's not the drive from the engine that's gone first.
