Power problem: not getting 24V

@fcwilt Yes, only the WIFI antenna was connected.

Well that suggests something on the board has failed and is shorting out the power supply - thus not voltage is measured on the board power in pins.
However I don't know the board hardware well enough to know what that might be.
@dc42 would surely know.
Is there anything on the board that looks burnt or swollen?

Not that I can see of.

I don't see anything either.
Well it is possible, though not likely, that the power supply has failed in a way that prevents it from putting out any power under load (when connected to the duet board).
Do you have another power supply you could try?

@asen Tomorrow, I'll try in the lab with an 5A 30V Adjustable DC Power Supply. Should be okay to test with, I think. I'll post my findings/measurements.

Have you tested the fuses for continuity?
Do you notice any components getting hot when VIN is applied?
What LEDs light up when VIN is applied? -
@asen Good news, when plugged to the LAB PSU, the 12V LED lid up. With nothing plugged into it, their is a current draw of 0.1A. I've taken a temporary 24V-6.5A PSU.
ps: Yes, I know the wiring is not adequate, it was just for a quick test. When used with a PSU all my cables are crimped.
To do: Test it with the new PSU, if everything works as intended I'll write it.

@phaedrux Yes, if you're talking about the two big fuses by the VIN port. Both are still good.
Nothing is getting hot. For your last question I kindly refer you to my latest reply on this thread.
thank you -

@fcwilt Yes, just tested with the new PSU. Works again, Thank you for your help. This thread can be marked as solved.
