Took it back to goodyear and told them I thought it was possibly the tensioner or belt needed looked at and they ran a system check on the charging system and stated at idle the volts were at 8, and when reving they were at 14. They said its the alternator, but I just had the alt replaced about 6 months ago. The last time this happened with a intermiedatly battery light it ended up being the mega fuse, I told them this and they said all the fuses checked out and it only took them about 5 mins to check which I think is crap. I asked them if they phscally looked at the mega fuse and they said they just ran a fuse check and everything checked out. So I dont know, but have a feeling its the mega fuse. Does anyone know by looking at the fuse if you can see if its blown? and can I reach this fuse by removving the air tubing and is it right below the TB? I want to check it my self and if its bad replace.
