1999 Ford Taurus

99 Ford Taurus SE, automatic.

Battery light comes on right before car shifts and then goes off. Battery is new as of Feb 2002. 73,702 miles on car. Any idea why this is happening? Is it a bad sensor or a lose connector or something? No power loss is felt and the car always starts right up. This is my girlfriend's car and she gets nervous, this is something I would probably just ignore but she feels insecure driving it.

You likely have some alternator problems and need you have it tested thoroughly including the diodes. The light could be coming on for high voltage also. the higher RPM when it comes on might elude to that.

yeah, sounds like a bad voltage regulator... it's integral with the alternator, but can be replaced separately.

Warning: Fighting the brushes to install the regulator can be very frustrating....
