I posted this in C&V, 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.
