Which wire is the positive pole in the turn signal circuit of Haval H2?
2 Answers
The red-colored wire in the turn signal circuit of Haval H2 is the positive pole. Below are specific instructions for using turn signals: 1. Left turn signal: It should be activated in advance when making a left turn, changing lanes to the left, preparing to overtake, departing from a parking spot, or making a U-turn. 2. Right turn signal: It should be activated in advance when making a right turn, changing lanes to the right, returning to the original lane after overtaking, or parking by the roadside. 3. Accident liability: If an accident occurs due to the driver's failure to use the turn signal, there is a high probability that the driver will bear primary or full responsibility for the accident.
With over two decades of experience in the automotive repair industry, I can tell you that the positive wire for the turn signal circuit in a Haval H2 is typically brown or yellow, directly connected from the flasher relay output to the bulb control signal. When identifying it, don't rely solely on wire color because color codes may fade due to aging or modifications. I use a digital multimeter to test voltage: connect the black probe to the vehicle's metal ground and touch the red probe to the wire terminal—the one showing 12V in DC mode is the positive wire. In daily repairs, most turn signal failures are caused by blown fuses or burnt-out bulbs, with wiring issues being relatively rare. However, incorrect wiring can easily lead to short circuits and fire hazards, posing significant risks. I recommend regular maintenance checks on the lighting system—safety first. Before attempting DIY repairs, consult the Haval H2 manual online or seek advice from a specialized repair shop to avoid mistakes.
