bike computer puzzle

I've got a Sigma 1106 (wireless) bike computer. It stopped working for no apparent reason the other day, so I replaced the battery, reset it and all seemed fine. The fixing to the bike is a push and twist arrangement which locks the computer in position and brings the two metal contacts into contact with the corresponding points on the bracket. When i twist it the final distance - i.e. click it into place - the screen goes blank, but returns to normal immediately the unit is removed.
I'm baffled, have any of you lot got any bright ideas?




  • sounds like an electrical short somewhere in the unit. When the 2 connectors are connected and passing a current it's cutting out....

  • Could have been an electrical interference causing the problem
