What you will learn
- Apply a structured measurement workflow
- Record results so they can be compared
- Decide the next test from the result

- Predict the expected value from Ohm's law or the manufacturer data.
- Measure at a known good reference point first.
- Move the probe along the circuit to isolate the loss.
- Record the number and compare with the expectation.
- Decide the next test based on the difference.
CASE 002

Key points
- Predict, measure, compare, decide
- Record actual values, not "OK"
- One variable at a time
All values shown are training examples. Real thresholds depend on the manufacturer, engine, temperature and system — always confirm with the vehicle service documentation.
