A common and powerful electrical troubleshooting technique is to by-pass suspected bad components. This is done using what's called a jumper wire that is placed across the contacts of the component, typically a switch of some type. You can buy a bag of jumper wires at Radio Shack or just make your own.
With this in mind, I present you this illustrative and thought-provoking photo. Can you answer the question it asks?
Okay, here's the answer:
The first three are ones I use, the fourth one is used by someone that should NOT be any where near electrical work................... DO NOT be that person, use an insulated 'jumper'....... Okey Dokey ....
