This sounds like either an alternator issue or the brushes in the alternator. I am going to attach some troubleshooting videos.

Dehumidifier squeaks when running

Disconnect it, (DO NOT REPAIR WHILE CONNECTED), remove outer plastic casing (screws), lubricate moving parts with a little WD40 or similar. Re-assemble.
If you can get to the part that's squeaking with a long tube you could try spraying silicone lubricant spray on it without disassembling.

Mazda protege makes a squeaking noise when I start driving?

If your Mazda Tribute's engine has a rumbling noise when you start it, this is most likely from the drive belt. You will need to replace it.

Hey, just purchased some behringer ms 40 near field monitors and after a few hours of playing at around the 1/4 volume mark i decided to turn the bass up. As i did so the right monitor began to make a...

The setting of the volume controls bears LITTLE importance to the actual level the unit is being run at since one can send high levels INTO the units from the source. These are intended to be used in a studio for the audio engineer to listen to in a small room. They should really be no louder than a consumer BoomBox maximum.

A squeaking noise is not normal at a level such as mentioned however. You might see if the noise is from the speaker itself or possibly parts of the cabinet... Plastic parts are NOTED for squeeking and can be suitably lubricated.

Beyond that, since the units are new, you should be able to exercise your warranty.

My dryer squeaks

First you should try to determine what the squeak is related to, does it happen every time the drum rotates or more frequently. This will give you some idea of where to look. You should disconnect it , take off the top and get someone to rotate the drum by hand while you listen. Moving parts are dangerous don't put fingers in. Commonly the outer drum bearing or belt idler need lubrication. Don't lubricate the belt. More details if you provide more clues.

Hi, the sustain pedal on my Casio PX-830 has a constant squeak now after 6 months, any ideas on a fix for this? Thanks.

clean with q-tips and rubbing alcohol around the moving parts, let dry 5 min, and some graphite lubricant may help. graphite is a slippery dry powder good for reducing friction on moving parts. comes in a little tube, normally sold buy the key making dept at any store

2005 chevy Impala brakes sqeak loudly

You brakes are no longer any good. Most times, the squeaking and rubbing noises are caused by brake pad wear, but you say the brakes are fine. Otherwise, if by constant rotation speed you mean the squeaking/rubbing noise is present even when the brakes are not applied, you might want to get the wheel bearing inspected.
also check out -------- The most common would be a loose P/S belt. If it is tight but is still the source, it could be a restriction in the P/S system causing high pressure and resistance in the pump.
