^This, plus the voltage should also be less than 14.6V. In other words, you want to see a number between 13.5V and 14.5V

If the regulator is no longer "regulating" you will see a higher number accompanied by odd behavior of the electronics, lights, etc.

I don't know, that's for you to find out. Keep in mind that if the regulator failed and was putting out excessive DC voltages for long enough time it probably cooked your battery and most likely took other stuff with it if not more.

At a minimum, you'll need to check the the 4 mini fuses on the base module inside the module box.

Would it maybe be an issue with the lower harness since all my gauges stopped working?

No, but it does bump up the voltage regulator as being one of the prime suspects

I replaced my alternator with a factory one. Car still wont start. Battery, ABS and ASR lights are all still lit. Gauges still arent working either. Any other possible reasons why this might be?

Check for voltage and ground everywhere i.e. ground straps. Be sure to replace ALL the fuses (if not done already) with the updated copper core ceramic type such as those from Flosser. And as I said in post#13 at least check (or better yet just replace) the 4 mini blade fuses on the base module

Don't forget the weird little fuse on the back of the instrument cluster. That is a dealer only item, but costs next to nothing.
