This one is another one of those strips written by real life. I don’t remember exactly what we were doing. I think it was a tester of some sort and we were doing something a little more complicated than checking a battery. (Forgive me for not remembering the details but this was 8 years ago and I can barely remember what I had for breakfast today).
I was in the cockpit and another mechanic was hooking everything up like Julio is in this strip and what is written in this strip is exactly what happened. It took us a little while to figure out how to work our test equipment properly and tech reps were called upon but we figured the problem out eventually. At least that’s how I remember it.
