When I work on consumer electronics, especially a computer, something requires connecting to a power source at some point. Usually it happens to be in a location that if it doesn’t work it’s a pain to take out. That’s why I like this kit which I found at Fry’s Electronics. It’s titled UNIVERSAL TEST LEADS (12 TIP COMBO) #SA15 from Philmore in Rockford, IL. The tips screw into the wires on both ends! It even contains molex and alligator-clip tips. Very useful to have indeed.
