That approach is no less worrying than the idea of wrapping the fuse in some foil from a tab packet!
Buy a new fuse.
I don't suppose anyone does but I've lost count of how many fuses I've met that had failed because of - for a couple of examples - the extra current required by the motor to cope with wiper racks that had been packed with some sort of rainwater/old grease fudge-style mixture, then there are contact studs that overheat and become loose in their substrate in indicator stalks, headlamp switches and similar high current locations. This wasn't so well known when every stalk switch was assembled around a suitably resilient chunk of phenolic resin but these days, even the good Lucas-style switches from James Paddock are built with plastic cores and all it takes is one good drive through a dark, windy storm to create sufficient use to melt the switch and kill the fuse.History wrote:..//..I also don't make a habit of shorting stuff out.
In the case of this stuff, they really don't build them like they used to.
