I replaced the corroded battery terminals, I replaced the corroded battery tie down assembly, and filled the battery with water. Took it down to the Autozone. They checked the battery and the alternator, everything is ok, the battery is good, and the alternator under load at 2000-2500 rpms was fine.
But the battery lights flashes when I accelerate from 4k to 6.5k.
Any help, voltage regulator?
I have 95k miles on original battery and alternator.
