Update: My old way of labeling test leads was a mess
I used to just wrap a bit of tape around them and scribble with a marker, but after mixing up a 5V and 28V line during a King Air autopilot check, I bought a Brady labeler. How do you guys keep your bench leads sorted?
Wendy, tape and marker is not fine. The ink smears and the adhesive fails over time, especially near heat. That's how you get unreadable labels or ones that fall off inside a panel. A labeler with proper vinyl tape is the only reliable method.
