When some of the pilots encountered a reversing light that was not on, they couldn't start to figure out how to eliminate it. The current situation is as follows: There are three reasons why the reversing lamp is not turned on: 1. The front or rear circuit of the reversing switch (below the switch) is broken; 2. The switch is damaged; 3. The reversing light bulb (hereinafter called the light bulb) is damaged; a) Cause: Usually causes reversing lights are not bright three: 1, backup light switch (hereinafter referred to as inter) before or after circuit breaking switch; 2, switch is damaged; 3, reversing lamp (hereinafter referred to as inter-bulb) damage (b) Remedy: First, preparatory: 1, the power is in the connected state (with a horn or open the headlights to check whether the circuit is in the connected position); 2, the car?? Mang ê / br> two inspection methods and procedures: 1, the shift lever reverse position is set, if the light is off, remove the socket cover, check the bulb is intact; 2, if the lamp in question, the two check? Lamp grounding is good; 3, if the ground is good, the switch short circuit on the two external terminals, if the light is bright, it shows that the switch has a problem; if the light is off, the switch before and after the circuit has a circuit breaker; 4, check switch and before, After the circuit is broken: (1), with a 2m long wire One lap is connected to the outlet terminal of the main power supply of the fuse box, and the other end is connected to the terminal of the external terminal of the switch. If the lamp is on, it means that the switch is in open circuit; if the lamp is not on, the switch and the switch are on the lamp circuit. (2) Same as (1) but connect the other end of the wire to the outlet post of the external terminal of the switch. If the light bulb is on, the switch has a problem; if the light bulb is not on, the back end circuit is open circuited.
