I have an old electric clothes dryer that has some problems. I want to test it by turning on or "activating" one pin at a time. How Do I do that? See the photo for a clear idea of what I want to do.
Normally, the red circle #1 plugs in to red circle #2.
Can I plug in ONLY one line at a time, such as the YELLOW line that i colored in the photo.
Can I stick a copper wire in each pin , one by on, to "test it" and "turn that pin on"?
If not, then how do I do it?
