2006 Ford Mustang battery light coming on, while new battery and alternator testing fine. Why?

thanks. Might take it by tonight or something. There is a little corrosion on one connection. Might just buy new cables

may not need new cables if only corroded on the terminals or battery just clean it off,use a metal brush and make everything shine like new.

Alright cool. I'll do that. Thanks!

your welcome.post results.

Well that didn't work either. Light still coming on

have you checked all connections,including grounds?i know grounds don't sound like much,but grounds are very inportant.they must be clean,tight,and,free of any crap on the ends and clean where they hook up!did you take it and have it checked anywhere yet?make sure all connections are tight,battery,alt,grounds.

been a little over 2 weeks,have not seen a reply back.maybe they got it fixed!

SSM 12055 - 2009-2013 Multiple Vehicle Lines - Battery Light Flickers - Stays On - Low Charging Some 2009-2013 Multiple vehicle lines may exhibit low charging system voltage, flickering battery indicator lamp, or battery indicator lamp on. This may be caused by engine vibration or improper probing of the 3 pin wiring harness connector at the generator. These conditions can cause a loose or spread terminal on theharness side of the connection. Service tip using the purple male flex probe from Rotunda Flex Probe Kit (NUD105-R025D), or a male terminal from box 3, drawer C-16 of the wire terminal repair kit. If there is no drag felt when pulling the flex probe/terminal from the harness connector terminal, the connector can be repaired with wiring pigtail kit WPT-118 (14S411), refer toWiring Diagram section 5 for wiring repair procedures. Here is the special service message, I know it says 2009 - 2013 but its exactly what our cars do

Thanks for the info guys. My Stang has been doing this for a bit and I knew the charging system was ok but it makes you a little leary when that light comes on and your on a long road trip. I am going to check all my connections and grounds.
