Vitesse MK2 Rev Counter


Piston Broke

Recommended Posts

I assume this is a mechanical rev counter? With a cable from the dizzie?

 

Those use a magnet, spinning in the gauge on the end of the cable, with an aluminium disc close to it but not touching. There is a needle on the disc. As the magnet spins it induces an eddy current drag on the disc pulling round against a spring to indicate revs on the gauge.

 

If the spinning magnet touches the disc,then it would drag it all the way round, but this would also need the stops at each end of the dial range to be broken. Sounds like a major breakdown. Might be repairable if you took the gauge apart, or send it to a gauge repairer like Speedy Cables.
