My battery light comes on and then goes off
1999 MERCURY MARQUIS
I've had the battery and alternator check. They are both OK. The battery and alternator have been checked and they are ok.
have the same problem?

It may test ok with a voltmeter but if there is a failing diode in the alternator, then it is bad. I would look harder at the alternator.
