my alternator bearing took a crap yesterday on the turnpike, so a friend brought me a new one and i changed it right there. everythings been fine driving it today, but theres still a burning smell, is there something causing this one to go bad too? is there anything i can check?

Do you have the correct belt? Maybe it is slipping on the pulley. Should be #60635. Also, check to see if the wire from the battery to the back of the alternator is touching the exhaust manifold and burning.

As mentioned check the belt for the correct length.

Some replacement alternators that i've seen have a different size pulley than factory and require a longer or shorter belt. :dunno:

Did you check the idler pulley for a bad bearing?

 

[87gninpa]

belt is the gatorback in the correct length, idler is fairly new and seems to be fine. Ill check the wire from the battery when i get out there. Its a very distinct smell, ive never smelled it before, is it possible it got "stuck" in the hood insulator and im just smelling that? theres no smoke, just the smell

Smell

It's not that nasty cooked battery smell, is it? Have you checked alternator voltage output? If it's 16 volts or more(overcharging), that might be the problem.

If it has an eggy smell to it, check your catalytic converter. When they get plugged, they smell like rotten eggs. :cheers:

If the smell is coming from the alternator it will be too hot to touch. If it's within reasonable temperature when the smell occurs then it's something else. It might be overcharging from a bad regulator and cooking the battery. Test the back of the alternator while running to make sure it's putting out about 13v.

ill check the voltage tonight....is the regulator the plug that goes into the back of the alt? if not, what is it? i have a feeling it may be overcharging

The regulator i believe is inside the alternator. If you can drive your car to one of your local auto parts stores they can test it on the car. It would be best to call them first though to see if they can do it for you. :yup:

thanks steve, ill look into that....STOMPN 6, ill do that tomorrow, however, the funny thing is ive driven it over 300 miles since i replaced it, and not one problem, just the smell. Its not as bad as it used to be, just very faint when i get out of the car after driving it. the alternator is not hot at all either. ill get it tested tomorrow to be sure, otherwise, i guess everything should be ok.

How old is your battery and is it in good condition?

 

[87gninpa]

battery is about 6 months old and its an optima red top, seems to be in great condition....

 

[STOMPN 6]

Did you do the test that Orlando 87gn mentioned earlier in the thread?

 

[jorgeaponte1988]

Its the humdum lateral it connects to the feesin the bottom with leverage
