I thought it should be around 14.5 V.

So looks like the alternater is working. The Advance Auto Parts testing equipment passed the alternater.

I believe I may have a combination of weak charging, along with a battery drain.

Should have the voltage regulater in a day or so. Hopefully that will resolve the issue.

The charging voltage will drop from ideal due to temperature and/or load. 13.4 volts would only be too low with a cold alternator, no electrical loads, and a fully charged battery.
