I have a PG Ti600.2 and an Alpine 35x4 powering my system. In addition, my Alpine HU is an 18x4. I also have an upgraded Optima Yellow top. The belts are the old V-belt design.

My problem is that no matter what I do to the alt and the belt, I cannot get it to stop sqeeling. The pulleys and belt is lined up properly. I set, and re-set the belt tension. I also have tried various belt brands, but to no avail.

My system does not include a Capacitor...would this aleviate the problem? My theory is that the system is putting a too large load upon the elecrical system as a whole and the alternator cannot keep up with these demands. Thus heating up, and making the belt slip. Is this plausible? Is there another explanation as to why this is happening?

Has anyone had experiences with this type of problem?

Thanks,

Did you try to dress the belts? Are they new?

Yes, it is possible that the load from a system will place such a load on the alternator that the belts will squeal. No, a cap will not help. The only thing you can do is upgrade to a higher-output alternator... and check the alignment, and replace your belts!

Thanks DYohn - The belts are all new. Currently I am using Goodyear Gatorbacks, previously I have tried the Dayco Gold belts, and some other CarQuest and NAPA belts. I have not used belt dressing as it is considered a band-aid fix, and I'd rather find the source of the problem.

Since a cap is of no help...I'll put the $100+ toward a new Alt. The funny thing is that the Alt I have now is supposedly an upgrade ove the stock Alt that came on the car stock. The stock Alt was rated 80A, and the alt I have now is 100A+. But I suppose that is still not enough.

Thanks,

Yea a capacitor has nothing to do with your problem. It wouldnt matter what your running. The noise is not being caused by any of your equipment my friend.
