We were instructed on this test over 15 years ago when we bought our first 5ver and have been doing ever since. Just seems like part of hooking up now and do it without really thinking about it. I've seen people that don't preform the test and I've seen the results on their pickup rails, not a pretty sight! Guess I will continue to preform the test as long as I'm able to pull the 5ver around.
