Even if a fuse HAS blown, replacing it with a higher amperage one is not a good idea.
The whole idea behind fuses is, if more current is going through the circuit than the equipment on the circuit can handle, the fuse blows, protecting the other equipment. If you use a higher-amperage fuse, then you run the risk of damaging the equipment the fuse is supposed to protect.
Don't replace the starter fuse with a higher-amp fuse, unless you prefer to replace the starter instead. Because that's eventually what will happen. Better to find out what caused the fuse to blow, and deal with the root cause.
