Round back to square back alt

The Dart turned 60 years old this month so the possibilities are endless. My electronic ignition install is fine and has worked well for a year. The issue started with this alternator so I do not think the cause is wiring. If it wasn't for the occasional 18V spikes I would not worry about it. Battery is fine. Battery getting 13.5 to 14.5V mostly. I'll drive it over to my NAPA store and ask if they will take it back. Before this one I tried one from O'reilly and could not get it to charge. So it is true, there is new junk on shelves. FYI the new VR is a Standard Ignition VR101 from O'reilly. Thanks for your explanations and advise. I will chime back in with the solve. KG
