Bluenose:
Further to other's comments, you need to check first whether the problem is with the gap between the sensor and the magnet. To do this, you can remove the magnet from the spoke and wave it close to the sensor to see whether computer registers anything. If yes, you need to decrease the gap between the two piece as much as possible. You may need trying different parts of the fork/stays to find the optimal spot. If necessary, you may need to stack something underneath the sensor to raise it further out.
If you don't get a signal when you bring the magnet near the sensor (in the first test), then the problem is likely to be with the hardware. It could be a broken line, broken sensor, bad contacts between the head unit and its mount (Sigmas are notorious for their failure due to the "press and turn" mounting) or even a faulty head unit. In these cases, the warranty could help if there is no sign of abuse.
I bought a BC1200 about 2 months ago, and it went crazy after 10 days. I had to return it.
Good Luck!

Hi,
I have a Sigma 1600 bike computer. Over all it works pretty well but I've been having some trouble
with the sensor. Sometimes it gets knocked and won't register anymore. You'd think it would be
simple to fix (or I
did) but it seems to be very very picky and after 30 mins of trying (fiddling around) I've not been
able to get register again! Very frustrating.
Would anyone have any handy hints on what I could be doing wrong with what should be a very simple
procedure?
Thanks in advance
