I have seen all the issues people have with the seat bar sensor but I think my sensor is working because when I lower the seat bar I hear a faint click and the light comes on. But lately when I hit the push to operate button I dont get the loud click that indicates the brakes have been released. It is very annoying, there is no reliable way to get it to work, I normally just keep trying until eventually it works. Aside from replacing the BICS system what else can I do? Thanks, Trent
