No, not an alternator itself. A slipping belt driving the alternator and the water pump could though.
over charging or bad bearings its about to let you stranded change it
No
yes
Bad bearings in an alternator would make a grinding or roaring sound. If a Diode Plate is failing you might hear a buzzing sound in the radio that changes pitch with the speed of the engine.
no if your battery light is on and the brake light on then your alternator need to be change
Yes, those exhaust gases are extremely hot and can cause the alternator to overheat. Not only that but that carbon monoxide can enter the vehicle and kill you.
A bad alternator will make whats called a whirring noise. It could also make a low growl. This is just the bearings going bad. If your alternator is not supplying any power, it has nothing to do with noise typically.
Battery light usually means alternator not charging. Most common solutions would be be a bad alternator, bad connection, or loose alternator belt. If the battery and alt test ok than check the connections to the alternator and battery.
no a egr valve would not make a dead battery. a bad alternator or maybe a bad connection post to battery would make it die ,
Not likely but possible.
If bearings go bad on a alternator/ will make a grindind noise or long squilling noise.. but if only electronic's inside alternator are damage no noise wil be heard
You would probably toast the diodes in the alternator.
