thing.about the smaller pulley is.u might need a smaller belt. cause u might have some slippage due to higher spin rate

Its your battery sorry to say go to oriellys and get a batt and alt test it wouldnt matter if you change the pulley why you think it comes with bothgo get a load test and also , when you installed the alt did you upgrade the charging wire to 4 gauge with a 150 amp fuse? Major must

quit buyin crap batteries lol
its a chevy thing ..like i said until i externally regulated my alt i would be 14.6 driving.then at stops it would drop to 12.9..its pcm controled
Any 05 and chevy has a pcm controlled alt, it will go into economy mode and derate the alt. I had to get a module in order to make my dual alt set up work correctly
If it was PCM controlled he would have noticed it BEFORE installing the new alt. He said it was fine before the swap. Stock case rewound alt needs the smaller pulley as it has no output at idle.
I've installed a few DC alts on 05 Impalas and they were not PCM controlled. 14.9v all day at idle....
