The plug-in 100V will output 100V when the test lead is ground as per the manual. The LED does not lit so I suppose it's dead.
When a plug-in is inserted I can see the protection being grounded by the plug-in as expected, but the voltage output drops to 12V.
I'm expecting either the supply can't deliver the load, or there's something shorted in both the plug-ins. I'll probe Q3 to see if it's limiting.
?
