For the past week, my Cateye Astrale has had no speed reading. The cadence reading is fine. The
problem probably occurred as a result of removing the wheel. I had no computer problems in the
morning on the way into work. Near the office I picked up a puncture, which I repaired just before
leaving at the end of the day. After fixing the puncture, I had no speed reading.
The obvious first thought was an alignment problem between the magnet and the sensor. But the
alignment really couldn't be better. I've tried waving other magnets passed the sensor, and nothing.
The next thought was a broken cable. The cable has been broken in the past, so I wondered whether
one of my soldered repairs might have broken. I don't know whether they had or not - by the time I'd
removed the insulating tape from around the wires to check, they were certainly broken. So I
resoldered them, but no joy.
The next thing was to clean the terminals. Seemed a long shot, and sure enough it's made no
difference at all.
I think the most likely problem is a broken wire. There's no visible damage, but a wire may have
broken inside the plastic outer. But I don't know how to test for that, or how to work out just
where it's broken. Any ideas?
