this is gettin' old...

because of the high torque loads isn't there a support mount for the back end of the alternator? typical german design (ie vw but maybe not porsche) has two tangs, one at the front and one at the back and the bolt goes both to hold the alteternaotr in place....

just askin

Just thinking about your original question "Why did it work for a while and then fail immediately after the jump start?" Jumping another car can put significant load on the charging system. The alternator and belt will produce the most torque against its mounts when it is under the heaviest load. So maybe the mount bracket was gonna fail but the high torque load hastened its demise.
