Why did we stop teaching the pin test on old autopilot servos?
I was training a new guy over at the hangar in Tucson last Thursday and he was about to bench check a King KCS 55A. He pulled out the multimeter and started probing the connector pins for voltage, which is fine, but he never did the simple drag test by hand first. I mean, that old trick of feeling for binding in the clutch saved me so many times back in the 90s on the KAP 150 systems. He looked at me like I was speaking a dead language when I showed him how to rotate the output gear and listen for the telltale click. Has anyone else noticed the newer manuals just skip the mechanical checks and dive straight into electrical readings?

Sounds like the new guy just got trained on the electrical side first, which isn't really a big deal. Honestly the drag test is a nice shortcut but I'm not sure skipping it is the end of the world if the bench check still catches the bad servos.
