Transformer Help

Sounds to me like you have one or more of the bricks wired out of phase. Check the bricks to see that they are all phased the same. You can do this with a piece of wire made into a jumper and a voltmeter. The center terminal on the Molex plug is the hot terminal. You will connect the voltmeter to the center wires on 2 bricks at a time. Put the jumper across the other 2 wires (the commons). With the bricks plugged in you should read somewhere close to zero volts. If the voltage is around 32 volts the bricks are out of phase with each other. It sounds like you have one out of phase so the tests should pass on 3 out of the 4 bricks. The fix is to either turn the 120 volt plug around in the socket or wire it backwards on the problem brick or turn the wires in the Molex connector around.

"There is a date code heat-stamped into the bottom of the case near the plug of the 180W Powerhouse, at the time of manufacture. Any 180W Powerhouse with a date code of 2000 48 or lower is out-of-phase with other transformers."
