is their a con? i have my break light fuse as 30amps cause 20amps keeps blowing. will anything happen?
yeah its not wise to put a higher amp fuse in and this will cause you to blow fuses.
Putting in a higher rated fuse will cause something to either melt or catch on fire.
You do not put in a higher rated fuse because the correct rated one is blowing. You fix the problem.
