Ri,
    I think the ideal method to trouble shoot this problem would be to
temporarily install an amp meter in line with the fuse. I would want to know
how much current is going through the fuse.
    Two scenarios come to mind. Either the current is normal and you are
getting a spike due to a short or the current is running at near thirty amps
all the time.
