I retried DFU mode with another power cable for the supply of the (DFU-)macbook. I didn't get a error message yet but it seems to install forever. I will let it install overnight and look what it shows tomorrow.

You've said no S5 power rails present.
That means board is off.
I was expecting to turn on the board pressing power button, not viceversa.

Sorry for my very poor formulation! 🙈 Seems like I was too tired when I wrote my last post.
I was referring to the DFU mode - there it shows the following behavior: It's always in recovery mode. When I hold power button down it switches off for a sec,coming back to recovery mode.
But no reaction on pressing power button. No pulsing on the s5 rails or anything. Just PM_ONOFF_L going down.

Test the machine in normal mode; see if turns on/off with power button.
Check at least for pulse on the coils.

Thank you very much for your patience and your help! I really aperciate it :)

No response on power button.
Trackpad is always an. When i hold power button down the trackpad powers off for a second then back on again - without pressing power button again.
