7892 - I wanted to share some words of wisdom with you guys. First off, a short tidbit of background. As many of you know, I work in EMC (ElectroMagnetic Compatibility) testing on automotive electronics such as gauge clusters, super capacitors, DC-DC converters, etc. EMC and--to a lesser extent--Electrical testing is often jokingly referred to as "Black Magic" within the industry. While there are very controlled environments and procedures for said testing, often times the problems that arise are simply outside the realm of logic. I should know this more than most, based on my experience with EMC and my background as a maintenance technician for complex electronic equipment in the Navy, and I've seen more than my fair share of things that simply will never make sense.
Anyways...to keep an already long story short, the last few days of troubleshooting have reminded me to CHECK. EVERY. BOX. When you are having a problem in troubleshooting and are logically moving through all the applicable steps, be sure to check things that have little basis in logic. Especially when someone else tells you, "that could not possibly be the cause." That's not to say that a process should not be followed, but rather do not discount the improbable. If I had ignored logic--and my superiors' directions--I'd have reduced my troubleshooting time on this issue by +90%. CHECK. EVERY. BOX. no matter how crazy they may seem. If you can check/modify/replace/etc. a component within a malfunctioning system, DO IT and do it NOW. Especially when it comes to electrical/electronic devices, things happen that do not make sense. Remind yourself that Chapter 3 of the technical manual is called *THEORY* OF OPERATION for a reason; NOT *LAW* of operation.
Do not allow yourself to be forced into a specific mental pipeline. You will do nothing more than waste time and raise your blood pressure.

Have a great day, everyone!
