jizazz12 Posted April 30, 2011 Report Share Posted April 30, 2011 (edited) I have 300 amp amputator without the overdrive pulley myself, car is 07 Impala my voltage is 14.2 to14.6 at start up but after it heats up i stay rite around 13.9 to14.1, i was told by a few different people that it was normal for me due to the fact that my cars ECU doesn't allow charging until i drop to 12.9. I was expecting more myself with the alt and two batteries, i even tried looking into a mla or vcm but no one makes them for my car but i have no issues with it, seems to be holding up just fine.
