@[Jun] no problema.sorry but i ask for the fuses in the main board,not the controller board.i say its near the controller board just to be more easy to spot.but tks anyway

so i manage to know that its a double diode but i cannot get any more informations...

@FACE666, sorry. I did captures the motherboard of my Dreamcast, at least we can see its components closely.

Edit: we may have found one of the fuses, D604

- Principal motherboard zone (near the ports gamepad PCB)



- Left/Right motherboard section

@[Jun] its not a fuse.its a double diode in the photo(look at mark i made)

@[Jun] no need to apology.i appreciate all the help

With a little "BIG" help,i manage to discovery what is the diode
for all the user its this:
double Schottky diode, here's the datasheet of it:
https://toshiba.semicon-storage.com/info/docget.jsp?did=3349&prodName=1SS374

place where you can buy it:

Anyway, this diode is part of the FAN tachometer circuit, it's possible to bypass it by using a jumper , but of course the DC will lose its thermal protection, so it's better to the right thing.

i make a tutorial for this and the controllers ports:

Hello, its a great and brutal research work @Face666, many thanks for sharing your work with the community

What happened to me, its that he had a wrong concept what is a diode on a motherboard very very wrong concept so I see I will try to review this information and learn.

@[Jun] tranquila
