it's whining. I have an 88 XR 7. Normal?
Is it a new one? It souldn't whine so loud that you can hear it with the hood closed and the motor running.
Definitely not normal... Are you sure it's the alternator and not the power steering?
Where did you buy it?Just because you buy a "new" one from a parts store doesn't mean it's a good one.I went through 6 of the Autozone alternators before I fianlly gave up and bought a 3G and haven't had a problem since.
yeah its new, not a rebuild.
Put in a 3g and be done with it. The old 2g alternators are horrible.
Yep,
...just happened to me Last year---bought a new one--put it in and it whined. Took it back--had it tested and yep it was defective. Got another one--no problem yet. Unfortunately, it means more work for you. At least its not a starting motor or something like that!
I went back to the shop and said it was defective and to put in a new one. Mechanic said it whined because it's a bigger alternator and its taking in more air. Theres a lifetime warranty for it so I gues if it goes I'll just get another.
The 3G IS a great idea.My current 'Bird has one,and the project car will also have one.You just can't beat it.It's leaps and bounds better than the ones our cars came with.
your mechanic is a douche. take it someplace else, if they say its junk have them charge the old shop for the repair. :beatyoass:
You said you have a lifetime warranty,right?Tell them to change it,or give you another and you'll do it.Don't ask them,tell them.You don't want to be on the highway in the dead of winter and have that "more air sucking" alternator go out on you.
Since when do alternators take in more air. He's full of shiznit. Get a new one and put it on yourself. It's easy and it won't take you more than 35 minutes.
Sounds like hot air to me also. Whining is due to bearing noise as far as my amateur mechanic ststus is concerned---it won't last long like that.
Actually whining is usually caused by a dead phase. Alternators have three phases, and if one is dead (either by a bad diode in the rectifier or a short in the stator) it'll howl. The alternator might still charge but it'll only be at 2/3 capacity, and will not last long. I'd get a new one too.
My 88 Cougars alternator whined for two years.. but gave up recently.
What the hell are these 3g alternators I keep hearing about? I want one, where do I get one?
Go get an alternator for or from a 3.0 V-6 Taurus.Other than re-clocking it (takes about 2 minutes),it's a direct bolt on.You have to modify your harness,but you then have a 130 amp alternator.I've had mine on for about a year with zero problems,and I can run my lights,stereo,heater,foglights (four small round ones instead of two rectangle ones),window defroster,and the alternator easily handles it.It is one of the best upgrades I've done to my 5.0,and,one of the easiest.
