Having problems with your 1998 Mercury Grand Marquis ?
Battery indicator light blinks sometimes, in random ways, even though battery is good. Do you assume the sensor is old and unreliable? Or do you look for another cause?
Look to your alternator for a single plug in wire next to the main plug and make sure it's not loose.
