Charger for a mobility scooter. One charger not working, I opened it
up and as per image below it looks like some kind of fuse has blown.
Text on the board looks like 3A/2500AR.

Can anyone confirm and identify what I would need to replace.
I have limitations on electronic stuff but could probably manage to
solder this part if I can find a replacement.

As a temporary test you could just clean up the toasted bit of wire and
wrap some fuse wire between the two, with a dab of solder if you want.
If that vapourises there's probably no point sourcing and fitting the
proper fuse.
