How to Find the Positive Terminal of the Turn Signal?
1 Answers
To locate the positive terminal of the turn signal, follow these steps: 1. Turn on the turn signal; 2. Use a multimeter to systematically check for a 12V voltage with a regular on-off pattern—this will be the positive wire for the left and right turn signals. The turn signal is a frequently used light by drivers, clearly indicating the intended direction of travel to surrounding vehicles. In a car, the turn signal is located on the left side of the steering wheel. When needing to signal a turn, move the light lever up or down—up for the right turn signal and down for the left. Specific situations requiring the use of turn signals include: 1. Overtaking; 2. Changing lanes; 3. Making a U-turn; 4. Exiting a roundabout; 5. Pulling over to park; 6. Entering a highway.
