Mountaineerfan 44 Report post Posted February 20, 2014 Good evening! I replaced my alternator tonight with the same type I took off the car. Installation went great, and all belts are tight. Once I started it, it made a hellacious screaming sound, and I noticed sparks flying from the bottom front of the alternator. After investigating the issue, I looked at the old alternator. Apparently the blades on the front of the alternator had rubbed on the pivot arm and had shaved off a notch on each blade! It looks like the new alternator is doing the same thing. Any ideas as to why the alternator would not clear the pivot arm? I have a 302 with A/C, Power Steering. What alternator do you recommend? Thanks!
