Having problems with your 2006 Ford Focus ?
Battery light comes on intermittantly while driving I had the battery tested and alternator everything was fine???Is it safe??
You have an intermitt issue. Test battery voltage when light is on. More than likely alternator (also check the belt that drives it) or poor battery connection (must be clean and tight).
If all checks out ok i would bet the alternator has an internal problem.
