In the picture of the circuit board I see in the top left corner a gold colored trim potentiometer do you suppose it's there to calibrate those meter readings?

Joel Ashley:
Hayden, I don’t know if you ever resolved your PCB issue.  I regularly go into a circuit board searching for a faulty component, and have “fancy” tools, like LCR tweezers.  But an essential tremor confounds many of my soldering escapades with minuscule solder points.  And I’m minimally conversant in electronics despite multiple books on the subject.

I know this is late to the party, but if I couldn’t ferret out a problem with a board from our coach, I’d consider sending it to M&M, or at least consulting them:

I did for the most part, It shows some of the levels and such, the screen is still a bit dimmer than I would expect considering the CAT Engine Display which seems to be made by the same company is very bright. I would love to get it back to 100% but other issues on the coach are plaguing me as of late. Thanks for the link, I might look into it and see what they think. 

Joel Ashley:
The only issue with M&M is they understandably prefer to see the device installed, so they can best analyze its behavior.  That commonly entails taking the coach to them.
