Talked to Shon at 5 Star, our repair guy, and he guided me through the wiring. Sure enough, the wires near the battery, both the one going into a fuse box and the one coming out of the battery were frayed/damage. Just a little bit of jiggling totally killed the meter connection. A little electrical tape for a patch job and I'll let him fix it correctly during a needed maintenance checkup next week.

Thanks GolfCart for your suggestions. Fortunately, the batteries are still fine.
