Ford F-150 (2004-2008) :: Battery Light On And Whining Noise From Pulleys

I have 2005 F150 XLT 5.4 litre engine and my battery light comes on after letting the truck run on idle or sometimes driving.

Last Saturday went out drove it heater on and radio on I smelled something coming from the heater kinda like burning wire smell didn't think anything of it no smoke from heater (indicating the core was bad) no lights on the cluster nothing; went into the bank let it run came back out my battery light on. Drove it home and while driving the light goes off.

Opened the hood and the smell was coming from the alternator. So I turned the truck off. Let it sit for an hour or so then I took my voltmeter to see if the battery was good. The battery was 12.4v with engine off. Checked my battery connection for corrosion or loose connections everything was tight there was some dust on the battery terminals so I brushed them off. I checked the battery cable that goes from positive to the alternator where it connects to the alternator with that nut it was good, clean and tight.

So I started the engine up and I can hear a whining noise from one of the pulleys. Let it idle for 2 minutes no battery light so I put my voltmeter on the battery it read 13.8v, so I turned on the A/C, head lights, radio and the heater tried again the voltage dropped down to 11.9v then the battery light came back on. Also through all this my battery gauge in the cluster always stays a half way mark doesn't drop or go high. Next with the engine turned off I took the belt off checked the pulleys the idler pulleys seem fine and the belt doesn't show any glazing but the alternator was hot almost like touching a hot exhaust manifold.

So for the last 3 days I have been trying to come up with how to resolve this issue obviously it could be the alternator going bad but the battery has never lost a charge yet I let the truck sit for these past 3 days and today I started the truck and it started right up I don't see any dimming lights except it has a whining noise and the battery light didn't come on immediately I let it run for 5-10 minutes before it came on; I even drove it around the block and the whining noise gets louder every time I step on the gas. To me it's either I need new alternator, tension pulley is bad or the idler pulleys are bad but they turn fine.

Camry :: 2004 - High Pitched Whining Noise At Idle / Battery Light Flicker On And Off

Yesterday as soon as I started my car, I noticed a high pitched whining noise. As I drove, it seemed to stop, but as I slowed down and idled, it came back. After driving a couple miles, the battery light came on, so I turned off the AC, radio, and lights and it went off again, but as I sat at stop lights it would flicker on and off again.

Lexus GX 2004-09 :: 2008 - Battery Light Came On And Whirring Noise Pull Over

2008 GX with 42K and just driving home and battery light comes on and a whirring noise--pull over and open hood smell strong electrical smell--ok Alternator fried. Got it home and battery light off but still when I put a meter to my battery with engine running its only putting out 13.4V? should be at least 14.5-6 correct. Has to be Alternator cause of the symptoms and the burning electrical smell..

SO WHO has changed alternator and how hard was it? Im looking for it and I think its under the Power steering pump it seems left side engine looking at it.??

I just bought a truck, it has a whining noise while accelerating, stops while letting on the gas, does not do it in neutral even if i rev up the engine. Only whines while there is some force on it, ie.. accelerating, or going up a hill at any angle, and does it from about 10-15mph- atleast 60mph.

Ford - Explorer :: 2004 - Whining Noise Above 30 To 40 Mph - ABS Light On?

Purchased a 2004 Lincoln Aviator, AWD, 200k miles at an auction, I'm familiar with standard 4wd systems, but this auto AWD is confusing me.

Truck is auto engaging the AWD after 30 seconds of driving, if I reset it back to auto, it locks AWD 30 seconds later.

If I'm driving above 30-40 MPH this gives a pretty intense whining sound. I assume overheating the system. Last test drive put it in AWD disabled mode- I assume from overheating.

Truck wants to auto lock AWD no matter what, I don't seem to be able to do anything to prevent this other than turn OFF traction control- which then ends up disabling the auto AWD and telling me to see owners manual as well.

Truck does pull a little from needing ball joints, but would this tell the computer to engage the AWD constantly ? Any thoughts?

I'd also mention the ABS light is on- I'm guessing a speed sensor could throw this off as well? My code reader can't seem to connect to this aviator- it could connect to my old explorers, but not the aviator strangely enough.]

Prius (2010-12) :: Whining Noise Near Inverter When Charging 12 Volt Battery?

My 12 volt battery is flat. I attached my CTEK MXS 5.0 and started on the Normal setting. I figured (wrongly it seems) that having the battery charger attached would support in starting the car. The green light displayed when I depressed the brake pedal and I pressed the Start button, but everything went dim and the brake pump slowly wound into life. The Start button glowed was on but no other functions started.

I pressed Start again and the light went out. Now when I connect the battery charger, a whining noise starts from near the inverter. The speed varies; dropping from a peak and rising again, and there's probably a pattern to it.

I've disconnected the charger a few times and the noise stops immediately. I wonder if the car has not switched itself off. I've disconnected the charger and I'm waiting some period of time before connecting it again to see if something will fall asleep. If not, I'll just have to climb over the back and disconnect the battery from the car before I charge it.

Lexus RX 2004-09 :: 2006 400h Not Starting - Traditional Battery Replaced

Last week Wed my vehicle was not starting. Some lights would start to come on and then die out. I read the forums here and replaced the traditional battery. Perfect, started right up and no issues. Today, went to bring the kids to school and it did not start up. No messages, a few lights like before and it went dark. Is this an engine issue. I have not tried to jump the new battery yet as it is pulled forward in my garage. (Today being Tuesday and not even a week into my new battery). I looked around, nothing was left on so what is happening. It has just short of 80,000 miles on it.

Sonata NF (2006-10) :: Clanging Noise Coming From Engine And Battery Light Turned On

My 06 3.3 is having a problem with the pulleys. A few days ago something squealed, like a loose belt squeal. I put it off, then when I started it up this morning, I heard a clanging noise coming from the engine, and the battery light turned on. I checked everything out and saw that there is a pulley broken off which is rattling around the crankshaft pulley. I figured it was a pulley that had broken off, but all 7 pulleys in the car are present and accounted for. Incidentally, the serpentine belt is way loose, which would be why the car lost power and eventually died. Am I completely lost or did an 8th pulley magically appear in my engine.

Ford Wiring/Electrical :: 2006 F150 - Battery Light On / Voltmeter Spikes / Grinding Noise As 4x4 Engages

Problem with my 2006 F150 5.4 4x4... Voltmeter spikes, battery light comes on, grinding noise as 4x4 engages on its own then everything returns to normal after about 60 seconds. Took to Ford who replaced the alternator and battery, still doing it so they replaced the alternator again...they checked the wiring and replaced some other misc parts and don't know what the problem is. The problem occurs once every few days, after only a few minutes or after a few hours, completely random.

Camry :: 2006 LE 3.0L - Whining Noise As Accelerated

On the way to work the other day I noticed a whining noise that got louder as I accelerated. When I got to work, I checked to make sure the belts were all ok and they were. When I got home, I inspected further. The noise was constant and got louder when revved. It also got louder when the a/c was turned from on to off. I figured it was the a/c clutch. Shop confirmed it's the clutch and bearing. My wife and I have owned the car since it was new and now it has 93.5k miles on it.

Camry :: 2006 - Whining Noise From Under The Hood

We have a 2006 camry with he 4 cylinders at about 106,000 miles. All of a sudden, the car has started a loud whining or purring noise. I have checked all my fluids and the appear to be at proper operating levels and there is no leaking anywhere that I can see. I replaced the water pump last year but have not replaced a belt on the car. The noise starts when you crank the car up and sounds like it is in tune with the engine. The steering doesn't appear to be affected although if there has been a gradual change the ease of steering I may not notice, but it is not at the point of being a manual steering without power. I cannot hear it through the speaker (like a bad diode). No real performance change in the engine or transmission except when decreasing speed the downshift of the transmission is more noticeable, like the gnome is dragging the through the gears.

Camry :: 2006 2AZ-FE - Whining Noise At Lower RPM And Acceleration

So, my Camry just started making a noise today. I was able to find the exact noise it was making on YouTube, to use as a reference for you all. Basically, it's a low pitch whine that raises pitch during acceleration. Once at highway speed, it's completely gone (probably due to ambient noise).

No CEL or any other warnings. I just hit 75k on the car, and from previous experience, it sounds like it could be related to a bearing in the alternator.

Sonata NF (2006-10) :: 2007 3.3L V6 - Whining Noise In Steering

Have a 2007 3.3/V6. Had whining noise in steering. Replaced reservoir and fluid. Still has noise and steering is worse. Probably will replace pump next as it has 220k miles. Alldata shows the pump being located on top of motor near reservoir which is incorrect. Appears to be on bottom of engine close to firewall. Is this correct? Do you have to remove plastic wheel well to get to it?
