Mega STe cartridge port problem...

Looks blown to me but check it with a multimeter in continuity mode, you shouldn't get a beep, just open circuit.

Also, there is a ferrite core next to it, L204 it looks like, and it looks like the right hand end (In the photo) has a dry joint.

Gotcha. I'll take a look at that joint as well. Thanks much.

Okay, I removed the fuse and tested it for continuity on an Extech multimeter.

I'm getting nothing. Nada, zilch, zero. Looks like it's dead Jim. :)

So now to get a new one...

Oh just curious - do I need to worry about *why* that fuse blew?

Or is that something I need not worry about unless I put a new one
in and it blows.

Thanks.

Got it. Got the new fuse in and replaced the old one:

And it seems to be working fine now. The Robokit cartridge
and software is running okay. You can see it in action below:
