This
book that gives
real world explanations as to what is happening in circuits when
they suffer from a voltage drop that causes electrical and
electronic components to stop working as engineered. This book takes
the mystery out of voltage drop. It looks at Ohms Law without
complicated math, and provides a refreshing approach to a complex
subject.
If you are a
little rusty on the subject of voltage drop, and what can cause
electrical or electronic components to stop working as designed,
this is the book for you.
Contents:
-
What
voltage drop is and what causes it
-
How
engineering uses "engineered voltage drops"
-
Why
resistance and voltage drop are the major “trouble” in troubleshooting
-
The
limitations of the voltmeter and the ohmmeter
-
How to do
effective voltage drop testing
-
Why good
“continuity” never means “able to pass current”
-
Cautions
about open circuit voltage testing and continuity testing
-
How shared
voltage feed and ground return current paths affect troubleshooting
-
Why
resistance that is large enough to cause a problem in a circuit is an
elusive value
-
How to test
your meter to see if it can provide you with accurate results
-
Learn why
it is smart to do complete shared current path base system tests on
every vehicle exhibiting drive ability symptoms that cannot be
pinpointed with scan testing and code retrieval
-
See why individual circuit
testing should never be performed until after all base-system
testing has been completed, and all excessive voltage drops in the base
system have been reduced to an acceptable standard
You will learn how to improve your
troubleshooting.
