[QUOTE="AnthonyO, post: 8744412, member: 563887"] Like this one. He changed a cracked plug and it didn’t fix it. But look what did I have a 2004 XLT with the 5.4 A year or so ago, my dash light came on and I decided thatit was probably my alternator. So I went to the official ford parts website and they hadtwo options. They had a 110 amp optionand a 130 amp option. My window sticker (which I still have) clearly says 130 amp alternator So I went to my dealer (didnt order it from the website)and asked them. They said the only option for my truck is a 110-amp reman from motorcraft. I showed them my window sticker and I showed them the ford parts website (remember this is the actual ford parts website.. not someone else). The dealer parts guys were curious. They called ford. Ford says use the 110 amp. At this point, I could have gone two ways. I knew if I got the 110 I would wonder, so I rolled the dice and got the 130 amp motorcraft reman. It fit fine and the voltage was fine. But the red battery dash light was on andstayed on. Something was wrong. I took it to autozone to have them check it. Their meter said the voltage regulator was bad. So I went back to the dealer parts department and they were very cool. They gave me another motorcraft reman 130-amp alternator. Same thing. The voltage was fine but the dash light stayed on. I took it to autozone and the charging system checked out fine. The connector on the wire to the alternator was cracked, soI changed the wire harness from the alternator to the battery (although the crack was small and seemed unlikely to matter). Nothing changed. The dash light stayed on and the voltage was fine. So I went back to the dealer and got the 110 amp motorcraft reman. (which I had to buy... not complaining tho) And that did it. The voltage was fine and the dash light was not on. [/QUOTE]
