Hi guys

Got a Honda. 31570-VP7-A01 mother board here with a K0CA 7A fuse.
I cant find this fuse.
Question is what can I replace it with.. I know it AC 7 AMP fuse but what does K0 stand for?

Normal Blow Fuse

ok so I replace fuse check for short no short. plug in and boom the fuse blown again. so i checked again finding nothing, no issue no shorts no other blown component and since there is no short I can't inject volt.
so what me next move?

show more of the board.
you probably have a large transistor or driver chip with something shorted on it's output.

clean anything that's square and black to get a better look .

check the ceramic capacitors and large 3pin parts for shorts.
hopefully it wont be that big driver chip with the heatsink tab under it!
what is this anyway, a 3phase motor driver?

it for the docking station for a lawn morrow.
I found the issue, Like I said there nothing wrong with the board no shorts it blow because of incorrect volt.
250v was incorrect it meant to be 120 volt.
