How To Use This Manual
The next few pages describe how this manual is organized. They also
explain what kind of information the manual contains, what that
informalion means, and how to use it to troubleshoot electrical problems.
Circuit schematics break the entire electrical system into individual
systems, like the Low Fuel lndicator Light on the nelit page.
Only electrical components that work together are shown together,
so you won't be distracted by unrelated wires.
Explanations of the abbreviations and svmbols used in the schematics
begin on page [Fl. You'll need to know what they mean before you can use
a schematic effectively.
