Days after putting in a new starter, a wire in the ‘harness’ burned out and now the dealer says it’s not related to faulty work done in putting in the starter but to a bad alternator that needs to replaced… 99’ Infiniti I 30. Help!!
Sorry I can’t help you directly with your problem, but why are you taking it to the delaer? Dealers are no better (or worse) than independent mechanics for almost anything you might need done on your car. They will almost always charge more per hour and often more for parts and supplies. They also tend to look at repairs a little different than the independent.
A dealer may well recommend work that strictly may not be needed, but could be connected to the problem or maybe replace a part when a little repair would fix it ALMOST as good a new. There is no need to bring your car to the dealer for any service other than service that is going to be paid for by a recall or original warrantee. I suggest that most people would be better off finding a good independent (Not working for a chain) mechanic.
It’s been awhile since I replaced a starter, but seems like it would be hard to mess something else up. Just 2 to 3 bolts holding it on and one electrical connector. Of course, other things may have been removed to get to the starter. I would think it’s probably just a coincidence that the alternator went out shortly after the starter was replaced.
If the cable to the starter was not securely connected that arcing could have caused it to burn up.
