18-gauge solid (not stranded) hookup wire
from an electronics store such as Radio Shack, or 1/8-inch-thick bonsai wire form a garden store.
It is especially easy to create such an inadvertent short circuit if you are using multistrand wire, so all station wire and hookup wire
going into a wiring block is solid.
