Lets see... The fuse is connected to the battery on one end, and to
some string of components on the other end.  The fuse blows because of
a short to ground on the component side in some manner or another,
maybe.  Yet when I put a new fuse in it doesn't blow, so either the
short is very transient or goes away when the power comes back on?  I
suppose anything is possible.

I will carry a meter around in the car with me, and when it blows again
(it's Tuesday so I bet it will blow tonight) I'll check the fuse
holder and see if I can see a short to ground.  If so, then your
suggestion makes sense, and if not, then checking individual components
at that point won't help, yes?

Thanks for the suggestion.
