Possible dead short in alt.

It's a brand new alternator

315

Voltage Regulator

315

I imagine you replaced the alternator because of an issue. A lot of times, when the alt goes, it takes out the regulator too. Of course, you could have also gotten a bad rebuilt alternator, It would not be unheard of.
