This course will simplify and explain the basic electrical system in most vehicles we come in contact with There are basic laws we have to follow in order to safely service these systems and the theory helps us understand how the system is supposed to work, when it is working correctly. This makes finding a fault quicker and easier! Knowing what is out of place is half of the battle Ohm’s Law- the most important set of rules for electrical system knowledge.

Continued 12v electrical theory of operation and basic principals. We now know what Ohm’s law is and how to use it to determine specific, circuit information. Now let’s look at real world schematics and learn some symbols and how to determine the flow of electricity to a load.
