94 Astro van

[sub2weeker]

Ok.... so here is the problem, My alternator is a 240 H/O. it charges my battery bank of 10 batts in back. it used to be just fine. but my brother over filled my power steering fluid and at a show i was giving the vehicle gas to keep the rpm up and it overflowed due to the hydroboost. And my alternator just went into perminant squak mode.

so here is a list of things i have done:

1.) Sprayed all the pullies with brake cleaner

2.) Put on a new Belt 1/2in shorter

3.) Put on a new Tensioner Pully assembly

4.) used Belt dressing

5.) had my alternator guy put a new front bearing in it

and still when i start it up i get a little squack but it goes away until i turn up the stereo and demand power out of it. And i have 2 runs of 4/0, not 4 guage, 4/0 directly off the alternator to the back.

SO WTF?????

i cant figure it out.

i'm sure you already checked this, but are you sure it is your alt making the noise?

you know i oiled all the pully bearings and the airconditioner. but it only happens when i get heavy on the stereo and that alternator kicks it

I'm really just guessing here, maybe the tensioner pulley?

Maybe one of the Alt companys can chime in?
