I don't have a link...but I do have some info...the compressor clutch coil draws a fairly high current...add in the blower fan and the aux cooling fan...the alternator may not be able to keep the voltage up especially at or near idle...not even including lights, ignition system, sound system, etc...to keep up the alternator needs to have an amperage output of at least 115 amps...more is better..a good alternator shop can modify yours if it isn't up to snuff...I have built lots of 12SI delco's that do that easily.
