Every problem has a logical starting point to begin the diagnostic process.
We have 7 trucks and 10 trailers that we use for our mobile campuses. Inevitably, the lights stop working on one of the trailers and one of us has to figure out what happened. Here is a secret we’ve learned: Always start at the truck, never the trailer. When the trailer lights stop working, it is most often related to blown fuses in the truck. It’s a common mistake to get distracted and start looking at the trailer.
We learned that again this week after spending more time than we care to admit trying to diagnose trailer lights. It’s just too dog-gone easy to get distracted and start taking shortcuts in the diagnostic process.
Whenever you begin to diagnose a problem, always start at step #1. Never allow yourself to get distracted and wander into step #17.
Thanks for listening.
