Yes, the output of that model transformer is approx. 12 volts AC. As
you said, if he uses the DC scale on his meter it's going to read zero
volts.



Bingo. The label says 110 in, 12v out, but doesn't say AC or DC. When I
just put it on the AC scale, it was 12.0 volts. I saw the automotive style
bulbs used on some of the lights, and ass-u-med that it was DC.
