Jaccio Perfect Switch Harness (long)

[Earl Haury]

I've found that one can make a simple tool that's useful for diagnosing vibration related problems from a inexpensive "Electric Pencil Engraver" (those vibrating metal engravers). Simply install a 1/2" dia. x 1/2" long aluminum piece on the pointer and it's ready to use. Most of these devices have a stoke adjustment that effectively alters the impact force, something mid-range seems to mimic engine vibes pretty well. Simply "buzz" various components until the guilty party is uncovered. One caveat, there is the potential to break receiver crystals with direct contact - so use caution around the receiver.

On another note - simply isolating a vibration affected component isn't the proper fix. While vibration can damage radio components, anything that changes behavior by applying vibration is already defective!
