Default Lights dim under hard acceleration
My lights dim when I accelerate. Under normal driving the lights stay on fine. If I floor it at about 50mph after 3000 rpm all the interior and exterior lights dim a lot the voltage drops to about 9. When I let off it goes back up instantly any ideas

Have you gotten the alternator tested?

If the wiring and belt and stuff around looks OK, it would be the first thing I did.

sounds like an alternator that is on its way out to me.

IMHO
