Buy yourself a couple of these..

They come in a range of sizes.. solder some insulated flyleads with clips on them and attach across the old fuse mounting.
Each time it blows, you just reset it by pushing the button.

You can fault find a blowing fuse all day long without having to keep swapping out..

Great idea Gav but what do insulated flyleads with clips look like. I get the idea though! :)
