If your 1997 Mercury Tracer has a battery light that blinks on and off while the car is running, it most likely means that the battery is not charging. This could be an issue with your alternator.
To replace the alternator on a 1999 Mercury Tracer, begin by disconnecting the negative battery cable to ensure safety. Remove the serpentine belt by loosening the tensioner pulley, then detach the electrical connectors from the alternator. Unbolt the alternator from its mounting bracket and carefully remove it from the engine bay. Install the new alternator by reversing these steps, ensuring all connections are secure and the belt is properly tensioned before reconnecting the battery.
