Cadillac Deville 2000 Alternator Not Charging

Marcus’s Question: My 2000 Cadillac Deville stopped charging and went dead. I had the battery and alternator replaced, but the alternator still won’t charge the battery. The guys at Auto Zone checked the alternator on their machine, and it works fine. So it’s got to be something feeding the alternator. What should I check next?



Answer: Yes, you’ve got a stinker on your hands. SO, check all the wiring going to the alternator to make sure none are burned or loose. Of course, check the fuses to see if any are burned. Hopefully it’s something simple like that. BECAUSE in that Caddie, the alternator is ultimately run by the main computer, and are they Expensive. Occasionally I see one go bad and have to be replaced because the alternator would no longer charge. Let’s hope it’s just a broken wire somewhere instead.
