Tackling Electrical Problems Successfully
For nearly a decade, I've been helping technicians
around the country, and even internationally
via the Motor Age magazine YouTube channel and
sponsored webinars, develop their electrical troubleshooting
skills. In most instances, the elements
that are missing are the same that were missing in
my own skillsets when I was a working technician.
It
took a national skills competition hosted by my
employer to finally force me to realize how weak my
electrical skills were and motivate me to search for
the resources I would need to improve them to a
professional level.
I'm willing to bet that many of you reading MACS
Service Reports are in a similar position today. But if
you study what I'm about to share with you over the
next two issues, and take the time to practice the
techniques I'll describe, I will promise you that you
will, as I did, have that " aha " moment when everything
clicks into place, and it all becomes so simple.
And you'll never be apprehensive about tackling an
electrical problem again. v

The Fundamentals
In the majority of cases, I find a lack of understanding
of electrical fundamentals as the root of
the problem. And the misunderstanding started with
how many of us were first taught about the basics of
electrical theory. Let me say, right at the offset, that
I don't believe you have to be an electrical engineer
to successfully diagnose most of the electrical faults
you run into. But if your fundamentals are weak, the
foundation you are trying to build on will skew everything
you learn afterward in the opposite direction
of where you want to go.
