yea, its most deffinately your alternator. price around for it. like, go buy one from like napa or something, and then price some shops on the install.
you can probably find an alternator for around $150, and if you want to you could just install it yourself. hardest part of the install would be getting the rusted-*** bolts to loosen up
that happened to me when i had my accord. it also could make a wierd noise. i think i paid around 350 with install from honda. i still have the reciept so ill look for it for ya.
did we see if this got resolved? I got the "Christmas Tree" Tonight. I am going to get the charging system looked at in the AM ...... OOOOOOOOOOOOOOO i am hot on this one!
