Hello there

Although I’ve worked on Computers for some years!

I’m absolutely new to component level repair
, please help

A2485 no power
Stuck on 5v
No power whatsoever is going to both fuses. I’m stuck here. Surely power should be at least going to the fuse.
I have checked Continuity on both fuses, and they seem to be ok

Please help?

Thanks

First of all, welcome to the forum!

On the newer Macs, the fuses are placed on the output side of USBC power area.
You can't find any voltage there with a short on the main power rails (PPDCIN_AON, or PPBUS_AON), as in your case.
