Any additional power drain , even the application of brake-lights(R+L +middle "cyclops") is enough to produce a very heavy
"torque loading" on the comparatively small diameter alternator pulley . You'll see this w/any of these systems "ON" upon starting a J30 - headlights , stereo , a/c (a/c is usually delayed couple of sec.'s) ,wipers , windows , seats - especially for they are "always energized" and adj seats at or unison w/starting , and even a foot on the "always energized BRAKES.You usually notice if you quickly bring up RPM's to over 1300 - squealing begins to stop due to "physics" - for at a higher rpm - the hundreds of watts of power needed (in the case of a too loose belt = simply idling & all systems off!) less torque to the belt is needed , remember Torque x RPM = Power. J30 notorious ,go & get gator , or just brand new quality belt &CLEAN ALL incidental pullys the fan / alt /damper which it rides . G.T.
