STOP REPLACING PARTS. START FINDING THE FAULT.
A warning light comes on. A fuse keeps blowing. A sensor shows an unusual reading. The engine cranks but will not start. A power window works sometimes and fails at other times.
What do you test first?
Is the component actually defective—or is the real problem somewhere in the wiring, power supply, ground, connector, relay, or control circuit?
How do skilled technicians know where to look?
They don't rely on guesswork. They follow the evidence, test the circuit, interpret the results, and narrow the problem down until the actual fault is proven.
How Skilled Technicians Solve Automotive Electrical Problems is a practical guide designed to help you develop that way of thinking.
Instead of simply explaining what components do, this book focuses on how to diagnose what is actually happening inside an automotive electrical system.
INSIDE THIS BOOK, YOU'LL DISCOVER HOW TO:
-
Use a structured diagnostic process to approach electrical faults.
-
Trace circuits from battery → power supply → controls → wiring → loads → grounds.
-
Use a digital multimeter for voltage, resistance, continuity, and voltage-drop tests.
-
Find open circuits, shorts, high resistance, poor grounds, and voltage loss.
-
Determine whether the problem is a component, wire, connector, power supply, or ground.
-
Diagnose sensors using reference voltage, ground, signal, and live data.
-
Use DTCs and scan-tool information without automatically replacing the indicated component.
-
Interpret RPM, ECT, MAF, MAP, STFT, and LTFT during diagnosis.
-
Approach starting, charging, lighting, accessory, and engine electrical faults systematically.
-
Find intermittent problems caused by heat, vibration, movement, corrosion, and electrical load.
-
Build a test plan and decide what to test next based on each result.
-
Prove a suspected failure before replacing a component.
-
Verify that the repair actually corrected the original problem.
BUT THIS BOOK GOES BEYOND BASIC TESTING.
Good electrical diagnosis is not simply knowing how to use a multimeter. It is knowing where to test, why to test there, what the measurement means, and what to do next.
You will learn to ask:
Is power reaching the circuit?
Is the ground good under load?
Where is voltage being lost?
Is the signal correct?
Is the component receiving what it needs?
Can the suspected failure be proven?
The goal is simple:
TEST. INTERPRET. PROVE. REPAIR. VERIFY.
Whether you are developing your automotive electrical skills, building workshop confidence, or need a practical diagnostic reference, this book provides a logical framework for approaching electrical faults without unnecessary parts replacement.
You won't just learn what to test. You'll learn why you're testing it—and what the result means.
STOP GUESSING. START DIAGNOSING.
Get your copy today and learn how skilled technicians solve automotive electrical problems—one test, one measurement, and one proven fault at a time.

To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
We may withhold reimbursement until we have received the goods back, or you have supplied evidence of having sent back the goods, whichever is the earliest.
You shall send back the goods or hand them over to California Books, Fort Wayne, Indiana, U.S.A., without undue delay and in any event not later than 14 days from the day on which you communicate your withdrawal from this contract to us. The deadline is met if you send back the goods before the period of 14 days has expired. You will have to bear the direct cost of returning the goods.
