New alt and battery.

An Autozone alternator test sees 12v going into the batt, not the 13.5v they're expecting. We think there's a drain somewhere.

Other possibly related issue: recently the "maint required" light came on. Checked and there's no error code.

AC compressor and radio stopped working. No blown fuses.

My Question is: what could the "maint required" light mean, and could it be related to these issues?

Any voltage readings with a multimeter on the ac and radio?
