From memory BITD they were always a fiddle prone to failure in bad weather. The wheel part is magnetic, and the sensor is a coil with no moving parts. They need to sit close to each other. Weak points are the contact from the handle bar mount to the sensor (crimped if I remember right), and likewise from the handle bar mount to the computer (a very weak sprung friction connection).
Anyone have details on how the Avocet 30 cyclocomputer magnet ring works?

So the magnet will induce a current in the pickup, and
i imagine it then reads the frequency...but it's possible it reads the voltage.
If the sensor is faulty, its hard to imagine a fix, although it might just be a small coil

100% sure it's magnetic.
Just measured the coil via the computer mount contacts, it's 365 ohms
