Yamaha 100 four stroke blowing fuses

My 2001 Yam had a problem.

On Sunday had a trip out, stopped for lunch and came back to find no ignition or electrics at all. Traced fault to 30amp fuse in engine blown. Used the spare fuse and all was good. On way back to mooring engine started missing and gauges went mad with engine eventually dying. Tried to change fuse again but not having it with a lot of sparks and smell of burning! Got towed in and now back at home

Thinking a short somewhere or an issue with regulator rectifier but haven't had time to fully investigate yet

Anyone had anything similar or any suggestions for possible issue?

Thanks in advance

Friend had exactly this with his yamaha last year, needed to replace the entire fuse box due to corrosion behind it, I don't think it was too expensive but you would be best letting an outboard shop diagnose if you are not comfortable as replacing parts for sake of it will get expensive quickly.

I had to tow him in twice due to the fuse box, I can't mind the price he paid but was less than a few hundred I'm sure.
