12.3 volts with the battery at rest means it's dead.


This right here! I had some "electrical issues" myself around a year ago and through a lot of research found that a good 12 volt battery should be at least 12.5 volts and more like 12.6-12.7 volts. Another common mistake is to check a battery without any load on it. I have seen some read 12.5 volts across the terminals and then drop down into the 11s just by turning the key over. You may also want to check out your regulator/rectifier and upgrade to a mosfet unit as well.
