Thanks again for all the help fellas. The green light on the gsc 10 is now working when the spoke magnet passes. May have always been working but it was too light outside. I will be trying these other suggestions today. One other thing I did Not mention is the unit actually totally lost its charge after not being used for a while. This is the first time it's battery was completely drained. It is since the recharge that this has been happening. That is the only other variable besides the wheel change that sits between it workin perfectly and now barely working. Would this have an effect? It did still have past ride data on it. I will say a gain that I really appreciate all of you that have taken the time to try and help.
