I need to know some good sources of information about automotive electrical systems. I want to understand a little more about how relays work and how and where to use them, how to make sure not overloading a circuit and how to read electrical schematics. My future bombings going to include better headlights and headlight wiring, fog lights , driving lights reverse lights and some of these options with remote switches using relays. Any online sources or books to find ?
my understanding now is very basic and prolly just enough to get me in trouble. Sure don't want to fry anything or burn up my truck !

 

Here's a free online Basic Electronics textbook.

This link should tell you everything about schematic symbols.

Check with your local trade school or Junior College and see if they offer any basic electronics courses.

I say do a google search (or your favorite search engine) or go the library and checkout a book on basic electronics.
