What would cause an alternator to burn up?

One possible situation that could cause this would be a battery with a shorted cell. The voltage regulator stops the alternator output when the charging voltage exceeds about 14V. If a cell is shorted, then the voltage regulator will never shut down the alt, which could fry itself, and boil out the battery.

Can an alternator burn?

A foul odor of burning rubber or wires could indicate that parts of your alternator are starting to wear out. Because the alternator’s drive belt is under constant tension and friction — and because it’s close to the hot engine — it may wear out over time and emit an unpleasant burning rubber smell.

Can a bad cell in a battery cause the alternator to fail?

Originally Answered: Does a bad battery affect an alternator? Yes, usually… depending on how the battery is faulty it can cause the alternator to work extra hard all the time or it can cause it to have to turn on and off a lot more then normal.

Why does my alternator die when I turn it on?

Your battery is being drained and your alternator (new or replaced) is working overtime to charge the battery while the diodes are being damaged by the draw in the window circuit. Disable this circuit via the fuse and see what happens. If I’m right your new alternator should survive just fine until you replace the fuse.

What happens when an alternator fuse blows?

Vehicles use fuses to keep the alternator functional. These fuses blow out after a while or when there is a power surge. In these cases, your alternator would fail and your battery would not charge.

Why do you need an alternator for a new battery?

That is why a functioning alternator is a must for any vehicle. When people experience electrical issues with their vehicle, they’re quick to think it’s the battery’s fault. But if you have a newer battery and you’re still having these electrical problems, then it’s likely the alternator that is at fault.

Why does my alternator belt keep breaking?

The problem is that the alternator belt and pulleys are not too durable, which means they can easily break. Pulleys will typically last for a long time before they eventually get damaged from old age.
