Final answer:
The voltmeter should be connected in parallel with the starter motor during a starter current draw test, with one lead to the positive terminal of the battery and the other to the negative terminal or ground.
Step-by-step explanation:
When conducting a starter current draw test, it is crucial to connect the voltmeter correctly to ensure an accurate measurement of the voltage across the starter motor. The voltmeter should be connected in parallel with the device, which in this case is the starter motor. This means one lead of the voltmeter should be connected to the positive terminal of the battery (or the positive feed to the starter), and the other lead should be connected to the negative terminal or ground. By doing this, the voltmeter measures the potential difference across the starter without significantly affecting the current flowing through it, as the voltmeter has a high internal resistance compared to the starter. Leading to a parallel arrangement where the voltmeter's presence does not alter the circuit behavior appreciably.
