No adjustments here.

The 1K resistor wasn't meant to be put in series. I was trying to point out that a PSU without a load can put out higher than normal voltages, and meant to suggest that you put the 1k resistor as a load (parallel, not series) by itself, then see if the voltages drop back down to something expected. If it does, then you can add another load (i.e. a fan) and see if it drops further.

13.8v PSUs are simple circuits, usually meant to replace/simulate a car battery. Heck I need one of those; I have a CD stuck in my old CD player!
