I got a Sigma wireless computer in March. It worked fine until May. It started showing "Too many signals" I think due to power lines, recovered later in the ride, then stopped for good as I neared home.

I changed batteries, called Sigma, and finally sent it to them. They claim it worked just fine on their test bike.

I got it back today, reinstalled it, and got nothing on a 24 mile ride. I expected occasional problems with a wireless computer since I live in a city, but I am flummoxed by this. I know it's installed properly since it worked for several months.

If anyone has ideas as to what the problem might be, I'd love to hear them.

Thanks,
Pam
