If you don't want to take the course at a community college, I can give you some outdated but perfectly usable textbooks to get you started, and I can answer questions through our private e-mail. I also have "Notes Pages" I produced for my students that include the important points.

You can also find a lot of books at any library but they will never replace classroom instruction or especially the new fad, computer-based learning. Good instructors need to see facial expressions and gestures to gauge your understanding at that moment, then we tailor our "story" to be sure you're understanding it. No book can do that. No matter how well a book is written, the reader is always going to have questions that need answering or points that need clarification.

One comment I always made to my students is a mechanic who has a good understanding of electrical and has good troubleshooting skills will be able to find a job anywhere. My students have gone all over the country and have been successful.

near the top of the list. It looks good but I didn't get into it very far. There are some topics you don't have to worry about, like tube theory. Even knowing transistor theory is nice but it won't help you troubleshoot electrical problems on cars. Basic theory including Ohm's Law and open, closed, and complete circuits is what you need. Ohm's Law is really simple. It is 12 electrical formulas but only three of them are used regularly. The math isn't even that critical in troubleshooting. Ohm's Law is merely the relationship between electrical pressure, (voltage), current flow, (amps), and resistance, (ohms). When one of those three goes up, one of the other ones goes up or down.

See how far you get on the web, then holler back when you have more questions.
