not charging?

i noticed my battery has been just strong enough to crank the engine over on my 04 fourtrax 4x4 400. i put the meter to it and showed 11.50 at half throttle and went up to 11.80 when idle. what is the problem here? its a new gell battery by the way that was put on early this year.

Welcome to the fourm. Your rectifier is bad from what you told me. Do you have a maintainer for your battery? If not then I strongly suggest you get one like a Battery Tender they will keep your battery at peak charge when not in use. You can clip them on or hard wire them in with the ring terminal and have the plug coming out just under your seat like I do.
