Hi Levent,

Putting in a larger fuse will not make the wire feel any cooler. Power =
Current squared x Resistance. Which component of that formula do you think
was affected by a larger fuse? A fuse is a passive device which is nothing
more than a piece of wire which is designed to melt when a given amount of
current at a given voltage flows through it. In other words, you want the
fuse to melt *before* your wiring does or your insurance company is going
to own a very charred Audi. I suggest you have someone who knows what they
are doing take a look at what you have done just to be on the safe side.
