This is because the alternator functions with a belt and a pulley. If they aren't correctly aligned or if something is worn out, you'll hear them rubbing.
You might notice the smell of burning rubber or a smell similar to an electrical fire, which both signal that it's time to have your alternator checked out by a professional. When the pulleys, belts and accessories are out of alignment, they create excess friction which creates heat.
An overheated alternator can send too much electricity through the wires, leading to a burning smell. If you are unsure if you need a new alternator, the team at Autospark can help.
