the problem easy to duplicate? What
system(s) are affected when the issue
occurs? And, one of the most important
considerations: Do I have the correct
tools, equipment, and experience
to complete the job correctly and
efficiently? The answers to these
questions can determine if you will be
capable of realizing a profit on the job.
In this month's Tool Briefing, we will
look at electrical problems and discuss
some must-have tools you need to both
diagnose and repair some common -

easily resolved by simply cleaning
battery cables, testing the battery and
charging system, and replacing any
faulty components.
Other problems can be faults within
the wiring to the starter or issues within many of the computer-controlled
components including various computer modules or anti-theft systems.
Due to the many different scenarios
that can be computer-related, and the
many types of tools necessary to both
diagnose and repair these issues, we
will save that topic for an article sometime in the future.
