You're right. Somehow when I reassembled the power supply when I wasn't
testing it (just put it back together to move it out of the way)I put the
H745 in the WRONG SIDE. Therefore, I have it now hooked up to the battery
backup plug.
I am not sure how this has any effect on the voltages you measure on the
transformer secondaries.
Can we go back a bit, please.
1) What is the problem with this machine -- it appears you think there's
a PSU problem. Which output(s) are defective?
2) What do you measure at the (transformer) inputs to the regulator
bricks. Rememebr a (working) voltmeter has two leads, so you are always
mesuring a voltage between 2 points. What are those points? When checking
the transformer output, you connect one voltmeter probe to each of the
transformer wires at the regulator brick -- not between either wire and
ground.
