0V DC Port Guage

[Loving LSC]

Going to try and explain this the best that I can. Took the wrap off today, yay, and connected the batteries. I am certain I connected the wires to correct terminals as I idiot proofed it last season when I took the cables off. All 5 batteries were replaced at the beginning of last season and they are read 13V -13.7V on a meter. In the cabin the DC gauge in the starboard side reads perfect, the port side reads 0V DC.
Here is the kicker, I turned the radio on, killed the AC inverter, and the incoming AC shore power. De-engergize the starboard side DC, the radio stays on. Waited about ten minutes then de-energized the port side and the radio shut off. Energized the port side, radio came right back on. If I had 0V as the gauge shows, shouldn't that not happen? Is this possibly just a bad gauge? Any thoughts out there?

Update, come to find I am just stupid. So I figured it out, it is what I like to call a PEBGAF error (Problem Exist Between the Gauge and the Floor). It is my first season prepping this boat as I bought it last season. I was reading the Amp gauge thinking it was the Port side DC, forgot about the toggle switch to test voltage. All batteries are working as they should, guess I should slow down a little bit.

Learning curve is steep with a new boat.

Ya done good figuring it out!

Glad it was an easy fix! But just an FYI, batteries should NOT be reading 13 to 13.7 volts. That's too high. Either your meter is not correct or you were measuring wrong. You could see that while being charged, but checking voltage while being charged is not an indication of battery health. Load testing is better, but voltage (after a short discharge) is a good, basic way to check health. Directly at the battery, though.

Lazy Daze, that reading was with the charger on. Did not know that was not a good way to check. Thanks for the info.

Yes, it is and thank you. Went from an 85 wellcraft to an 02 340 DA, there are just a few differences.
