A flow chart says that a circuit is formed between terminals 3 and 8 with the switch in the UP position. This can be checked, without disconnecting the switch from the circuit, by using a:

• A. DVOM to measure voltage drop across terminals 3 and 8 with the switch UP
• B. continuity tester
• C. battery test
• D. multimeter set to resistance

Answer: (A)

When you want to confirm that a path between two terminals is actually formed while a switch is in a given position, the most direct check is to look for a voltage difference across those terminals with the circuit energized. Using a voltmeter (DVOM) across the two points with the switch UP lets you see if there is a live path as the circuit states, without disconnecting anything. A voltage reading indicates the circuit is indeed completing between those terminals under the switch position.

Continuity testing isn’t ideal here because it’s intended for an unpowered path and can be misleading in a live automotive circuit or when other parallel paths exist. Checking resistance would require powering down and removing components, which isn’t compatible with verifying the circuit in its operating state. Battery tests don’t specifically verify the connection between those two terminals in operation.
