Bad alternator?

[LBoogie]

Ok so about a week ago I was driving the ty, when I left to go home from eating it started making this whining noise...which I assumed was coming from the belt. Anyway I went home and looked at it, nothing seemed out of the ordinary except for the noise. Today I went to start it and it was completely dead, I jumped it and it ran fine. I drove around for about 20 minutes or so (still making the noise), came home and shut it down, tried to start it again...still dead.

So, I am thinking the alternator is bad...maybe the noise is coming from the pully?

any thoughts?

Nope, alternator bearings. Pull the belt and spin it by hand. Then take it off and have someone check it. Most will do it for free including Interstate if you can drive it there.
The bearing in either the tensioner or the idler pulley may also be making noise. Which, if they’re original I’d change anyway.

Re: Bad alternator?

If you mean dead as in no start, you could have both a dead battery and a alternator going bad.

BTW, I can't read any of your posts as my background is light grey (as I'm sure is the case for a lot of users) and the white is inreadable. I would suggest going back to default text.

Re: Bad alternator?

Take it to your local VatoZone and have them run a test on your charge system. They can tell you in a few minutes if it's your battery, alternator or both. If they battery deep cycles and/or sits for some time w/o a charge then you'll cash in your battery if it isn't already.

If you need an alternator I have a stocker that was used for about two months with no problems that I'll let go for cheap. PM me if you find you need one.
