Please help Me.."Overcharging"?

Oh wonderful. I have a 1971...
I was trying to read all of this from my phone in the garage earlier. So it was hard to see.
If I did cause severe damage, it will be on the craiglist if this alternator don't fix it. I will know when it gets here in 8 days. Now I am concerned of all that may be really wrong now. Damn shame. Car ran great till this incident.

Did you get your core back? Maybe you can just install a new pulley.
