Default Interior/exterior lights dim/flickering when high rpm

Got a 2004 blazer that whether it be park or whIle driving,if you hit the gas, don't even really have to punch it but gets worse the harder your pushing the more the lights dim/flicker. Interior lights and headlights definitely affected. Had alternator tested not too long ago but kind of sounds like there's a scratching noise coming from that area as well. Voltage to battery while running is good. Any ideas of where to start? Was going to go redo every ground I can find atm but if anyone got any other ideas let me know!!

Sounds like your alternator might be faulty. Take it somewhere and have it tested or your battery
