[DML] Re: The alternator

["cruznmd" <racuti1@xxxxxxxxxxxx>]

Have you spoken to the vendor of the alternator? My impression is that it's still 
pretty new. Maybe it's still under warranty.

As has been stated many times here, grounds are critical. The grounds 
complete the circuit. If they are dirty/corroded/loose, then your current flow 
will be restricted. Think of it as pinching off a garden hose.

I suppose it's possible to damage the alternator by running it with a poor 
ground because of the resistance involved but I suspect the alternator 
squeals because the bearings are nearly gone. Since this is obviously not a 
stock altnernator you must have made some alterations in order to make the 
pulleys line up for the belt. If you're even a small bit off (meaning you're 
diagonal), the lateral stress will wipe out the shaft bearings pretty quickly.

For my part, I can't understand all the hoopla about alternators. Mine was 
completely siezed when I bought my car. I had it rebuilt and fully loaded, it only 
dips down to 11/11.5 Vdc. Variaton within the species I guess.

Sorry I couldn't provide more positive info.
