Duet wifi module only works when connected to USB
I have a duet wifi (3.1) whiched used to work fine. A fuse within my electronics blew (which happened before, no problem to the duet, just loses power) and replaced it. When starting up the Duet wifi, the Wifi module does not work anymore, so I can't connect by Wifi (the light is also not blinking). When plugging in the USB cable, the WiFi module starts right away.
It used to do it without any problems and it looks like there is somehow no power. When only powering by 24V, the regular blue light is on.
How is this possible and how to fix it?

No red 5v light next to the blue Vin light?
Why does your fuse keep blowing?
Do you see any scorch marks on any chips?
@bearer @Phaedrux Apparently the hotend heating element wires touched each other, resulting in a blown fuse (the 7.5A). I noticed when powered by USB, there was still no current to the extruder heater when set on active. Waiting on my new fuse.
It worked. New fuse of 7.5A made it work again. Takes a few minutes after setting up to provide enough current to hotend
