One more thing................. Very good for testing the New GE Refrigerator boards. You can pull the connectors and these pins work very good to test the resistance of the thermistors to tell if they are sending the right temperature reading to board. Also good on any of the new washers where you have to test plug connectors or wiring harness. For these, I have a set of test leads with clips on them. Works well when you are by yourself and you have to check wires for continuity or voltage. I used them this afternoon checking a vertical modular washer (Whirlpool) where I had to see if all the wires were OK from computer to Motor/actuator down below. I jam pins into connector wires, then clip one meter lead to wire. (I have extra long set of test leads) Now I can easily check a wire harness, or voltage to certain components.
