voltmeters not working

[tkaustin]

2011 RT 25SC.
There's a panel of circuit breakers at the helm. At the top of each column there is a voltmeter. 12v on the left, 120v on the right half. After replacing the batteries in the spring, the 12v meter has not indicated anything. Switching thru the 3 bank selector switch, it only comes up with zero.
Did I fail to connect a voltage reading wire to my batteries? There's nothing hanging loose there.
Where do these meters get their voltage sensing from?
Thanks.

Should be a wire to each battery buss. They also have in line fuses. Did you replace Batts yourself?

Yes, I did R&R them myself, so I'm the responsible one. And I drew a picture of each connection while labeling the cables, so I have high confidence they are in the correct places.

I did the same thing right after I bought the boat. Took cell pics of everything, figured all cables out, labeled them, and drew schematics. On my boat the meters were landed on the battery buss. Individual 14-16 ga wires with a 3amp in line fuse. I can't imagine all three fuses blowing at the same time. Sorry, no further suggestions.
