Basic automotive electrical theory and diagnosis.
Most conventional vehicles use a 12 volt negative grounding system. Many of
the cars and trucks today use many different computers, modules, relays,
switches, sensors, wiring harnesses, etc. to control and monitor vehicle systems.
Computers are used to control everything from engine management, emissions,
ABS, Airbags, lighting, audio, windows, doors, and so on.
Testing electrical circuits is a very important part of vehicle diagnostics in todays
cars and trucks. Most all systems on todays vehicles are electronically and
computer controlled.
A good solid knowledge of OHMS LAW is needed to understand how to diagnose
electrical circuits and understand the results of the testing.
A scanner, test light, Digital Volt Ohm Meter(DVOM), and schematics are the
basic items need to properly test todays complicated electronics.
Improper testing can cause more damage to a system than the original problem.
Intermittent problems are the hardest to repair and require a Techician who is
very familiar with whatever vehicle he / she is working on. Experience is
extremely important. Vehicles change from year to year and model to model.
Schooling is a very important part of out career.
