Those of you that are on discord have probably seen me write about this 

Recently got myself a fuel and upon trying to turn it on nothing happens , no lights no fans nothing 

Jumpering the PSU makes it turn on and output all the correct voltages (suggesting its not the faulty PSU)

Connecting to the L1 via a usb to serial cable doesn't seam to work , I get no output 

Does anyone have any idea's ? 

regards
