Same voltage across all red and black terminals, no throttle control.

Maybe this will help. This is for the original CW-80, not the re-release that came out a couple years ago.

Simple, you blew the output devices. They short on when blown in many cases. BTA24-600CW
The bigger question- do you still get a power status LED? I'm asking, because many failures, if the voltage backfeeds into the microprocessor, it blows it and shorts the 5V logic voltage supply. The processor is not a part we can replace because we do not have the firmware to flash to the new part.
Again, output device failure =possible fix
No light= this just became a constant 18V supply.

This is also pre-2006, showing that the red posts A & B are common, instead of the 2006-up black(U)-posts-common version.
Also, in my experience measuring using a meter- some units have more "bleed" than others, so a load like a light bulb is very useful.
In other words:
#1 ensure your wiring and the version of CW80 you have is not bonding the 2 outputs because of red posts being common. Again, it's possible that a red post common in certain wiring situations could appear as bleed or constant on because of the shared common post.
#2 Don't fool yourself by just measuring with a (edit) high impedance digital voltage meter, that the output is not "throttle" controlled. You need a slight load- a single bulb will work.
Do yourself a favor.Make it a doorstop and get a better transformer.
The cw-80 is the oddest transformer ever created.

Actually, that would be a high impedance digital voltmeter, but the advice was sound, add a light bulb for an accurate measurement.

Good catch!
