I posted this in C&V (http://www.bikeforums.net/showthread.php/793742-Avocet-20-computer-new-battery-but-no-legible-display), but I will try here, too.

I have an Avocet 20 cycling computer. I obtained this computer when I purchased a vintage bike, but I have never seen this individual computer work. I do not know if it was damaged when I got it or not. After searching, I was able to locate the manual here: http://www.avocet.com/instrpdfs/pdffiles.html. I purchased a new battery that matches the old one and the number on the Avocet website (386).

However, I cannot get the display to work with a new battery. A few faint, non-identifiable characters appear when the battery is inserted and then fade out with the LCD turning back to gray.

I opened the back and looked at the board on the inside. It looks very good for its age: no corrosion from battery leakage or other oxidation.

I'm wondering if someone out there has taken apart their Avocet 20 computer and could tell me if there's a way to get these working.

Thanks,
Tim

I have one of these and it still works. It was THE computer to have in the mid 1980's.

I don't know enough about the details of these but I suspect somehow a component has failed. You can probably find a NOS or used one on EBay if it's important for you to have one of these.
