Electric Variometer reading backwards

Is it possible that the variometer is in cruise mode when you expect it
to be in climb mode or vice versa?Â* Is there a Climb/Cruise switch on
the stick or panel?Â* How about such a switch on the flap system that may
have come loose or lost a wire?

I have an issue with the electric variometer in my Libelle. I believe it is a Winter -- I will look up the exact model when I get a chance to visit the gliderport again, but for now, I was wondering if anyone has some idea what might be going wrong.

The following description has been confirmed by referencing my altimeter over time during climbs/descents and my mechanical variometer that is working correctly.

When I am climbing, I get "climbing" tones that have a higher pitch the faster I climb, but the variometer needle is pointing down. When I am descending, I get the slow, low-pitch "descending" tones, but the needle is pointing up. The proportions seem correct, but the needle is pointing in the opposite direction.

My thoughts are that the computer is pushing out correct data, considering that the tones are correct, but it is somehow reversed going to the needle. I wonder if the two wires could have been reversed during maintenance by a previous owner, but if that's not what happened, I'm afraid that if I swap them, it might break the computer or variometer.

Again, sorry for the lack of specifics -- I will try to post them later. But for now, has anybody heard of this error before, or do you have any suggestions?
