If I buy about a 250amp alternator from you guys for my 2002 Suburban 1500 LT do want my old alternator also as a core? I’ll be running 2 amps at a total output of 800 watts maxed out.

You didn't show what the alt was putting out when it had the load at 12.8v, so when you put a 70a load on it. . What is it both alt putting out?
