no guys the purpose of fuseable links is not job security for dealership techs.

the above post about short term overcurent draws is correct.
when some electrical devices such as the starter are turned on they have a really big spike in current draw. if they were on a regular fuse they would blow every time you turned the key.

If you burned out a fuseable link i would say that you have a huge draw somewhere that draws for sometime at the high amperage. find out the problem and get it fixed! don't just put a regular piece of wire in it's place. bad things can/will happen.
