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 introduction is as follows:
There are three reasons why a reversing light does not come on:
1. The front or rear circuit of the reverse switch (below the switch) is open circuit;
2, switch damage;
3, reversing light bulb (hereinafter referred to as light bulb) damage;
(A) the cause of the failure:
There are three reasons why a reversing light does not come on:
1. Reversing light switch (hereinafter referred to as switch) circuit break before or after;
2, switch damage;
3, reversing light bulb (hereinafter referred to as light bulb) damage;
(b) exclusion method:
First, preparatory:
1. Put the power supply on (use horn or open the headlight to check if the circuit is in the on position);
2, the car?? テ鸩 9. Tan 茫 茫 BR? BR> Second inspection methods and procedures:
1. Set the gear shift lever to the reverse gear position. If the light is off, remove the lamp holder cover and check that the light bulb is in good condition.
2. If there is no problem with the bulb, check if the two bulbs are grounded.
3. If the grounding is good, short the two external terminals on the switch. If the light is on, the switch has a problem; if the light is off, the circuit before and after the switch has a circuit breaker;
4, check switch and before and after the circuit breaks:
(1) Use a 2m long wire, one lap on the outlet terminal of the main power supply of the fuse box, and the other on the terminal of the external terminal of the switch. If the light is on, it means that the switch is open circuit; if the lamp is not Bright, indicating the switch and switch to the light bulb circuit has a broken 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 bright, there is a problem with the switch; if the light bulb is not bright, the back end circuit is open circuited.
