Wow i really screwed up the title on this...
Anyways
Reason why I'm asking is that on the way back from Dark Knight this evening, my car started making a weird noise only around 1200-1500 rpms. I can almost compare it to a hydraulic pump kinda sound. I got back from the movies and looked all around under the hood but I could find nothing. So I took the car out again and did a pull at waste gate pressure, pulled over, and shut the car down to look if I could see and smoke or anything; there was nothing. When I started it again car it struggled to turn over but started. Got back to my appartment and there was a bit of a burning smell but no smoke. Turned the car off, tried to start again and it clicked but would not turn over.
So does this sound like an alternator issue? I am assuming so because it would only make sense the car is dead from running on battery power instead of the alternator. The car has 83k on it and has never had an electrical problem.
Do these things make noises when they go out? Do they fail this sudden?
Thanks
Chris
