I just bought a Sigma 1606 bike computer for one of the Guzzis. (In case you don't know - yes, you can use them on motorbikes, they go to 200km/h.) I bought the top of the range 1606 because it has a backlight. (It also comes with an extra pickup and magnet for the cadence display. So I have a spare pickup. Also the cadence magnet is different to the spoke magnet, and it easily sticks to the brake rotor. Much better than the spoke magnet.) Getting back to the backlight: It's very good, but it only comes on for a few seconds after pushing the button. I figured a wire or two soldered on to the cct brd will fix that. But I can't get the thing apart! Has anyone else done this before?? Any suggestions on getting the thing apart appreciated. (Other than "use a hammer" and such.) I also plan to hook up a 3V supply from the bike - but I figure I'd tackle the hard part first.
