My 99 grand marquis just had a new alternator on. The wire connecting to the top was very mess up. Cracked and pieces falling off. I replaced the alternator and now while driving my voltage meter goes up and down {most of the time down}. The alternator is only sometimes charging the battery. Please someone tell me now. Its my only car! Thank u

Are you talking about the large 3 way female plug that plugs into rhe alternator? sure if so, that is a common problem on many Ford products. Your local auto parts store can sell you a replacement pigtail for that. You will just need to cut the old one off & using butt connectors, which should come with the new plug, wire it into the harness. Then you should be good to go. HTH. -Jim
