My home's voltage measured 123.3V AC during the powerline voltage test so I wired the power transformer as per page 25 (115-130V AC). However, when I conducted the transformer secondary test (page 29) I got only 3.37V AC across T7 and T9. However. the reading across T11 and T12 was well within specs at 181.8V AC. I rechecked the voltages several times and re-positioned the alligator clips to make sure the connections were good, and but T7/T9 readings were pretty consistent (3.36–3.38V AC). Checked all soldering joints under a magnifying glass and they seem to be OK.
I read in a previous post that some multimeter's don't read low voltage AC very well, although mine is fairly new (bought a year ago).
Any help on what the the problem might be would be greatly appreciated!
