Just installed my new alt, before I was dropping to low 12's full tilt on a stock 130 amp alt. Installed my new 250 amp alt, which was tested at 279amps at 1800 rmp, but still same voltage drop? Still low 12's. Im running a SQ3500, which is around 4krms at 1 ohm and I have around 320ah to back it up. Does this voltage drop sound reasonable? Why not even a little better voltage?
