When I turn off the car, there is usually a slight buzzing noise still going on. But usually when I come back to the car, that sound is gone. Now it is going all the time, and running down my battery. What is it, and how do I turn it off? Thanks.
JA: Have you tested the battery with a voltmeter? And can you see if it's leaking or not?
Customer: I have had the battery tested, and it tested fine. No leaks that I can see. When I connect the multimeter to it right after I turn off the car, it goes 11.21, 11.20. 11.19 real fast. And inside the car, still that buzzing. One hour later, it is still buzzing, and battery about 10.77.
JA: What is the model of your '11 Jaguar?
Customer: 2005 X-Type
3.0L 6 Cylinder
JA: Are you fixing your X-Type yourself? What have you tried so far?
Customer: I have cleaned the battery posts and reinstalled the cables. I was thinking it was the alternator
. But when I drive it, the voltage goes back up. It just drains with the car in the off position with that buzzing still inside.
JA: Anything else you want the mechanic to know before I connect you?
Customer: That is about it.
