I have a 1997 ford taurus and the battery wont stay charged I have had both the battery and the alternator checked they are both good I cleaned all the ends and replaced the main fuse going to the alternator but it slowly keeps going dead I took ou the radio all the bulbs and checked all the wires but it is still doing it and the alternator is making a whistling noise do you have any idea on what it could be

Check fuse 11 in I/P panel and fuse 26 in engine box. Do you have a volt meter? If yes check voltage at ATL connector. Engine 3.0L 12V or FFV?

Yellow/white comes from Mega fuse 175A suspect wire connection bad. Either trace wire and repair or run new can be hot all the time. Ues MEGA fuse for source
