1. Fault characteristics of xenon lamp ballast
Fault 1: After installation, the headlights work normally, but the headlight fault warning light on the dashboard lights up
This is a very common fault, which may be due to the mismatch between the xenon lamp and the ballast. The xenon lamp and ballast of the same voltage should be selected.
Fault 2: After installation, the bulb flashes or often goes out or the left and right lights are not lit at the same time.
Most of these faults are caused by the wiring The problem may be caused by the excessive starting current of the ballast. At this time, it is necessary to check whether the working current of the headlight circuit is normal.
When the ballast squeaks during operation, it is the sound of the transformer inside the ballast, which is normal. However, if the sound is too loud, and the cover can be heard outside, it means that the transformer still has quality problems. Please rest assured that this does not affect the use. If it is serious, you can replace the ballast.
Second, the method of judging whether the ballast is damaged
1. When the xenon lamp does not light up, unscrew the light bulb that does not light up and replace it with a new one , if the new light bulb is on, it is a problem with the light bulb; if it does not light up, it is a problem with the ballast.
2. Check the interface of the ballast harness. If the socket is loose or there is a problem with the line, the ballast will fail; if the plug is normal, it is the ballast.
Three, how to test the quality of the xenon lamp
1. Light bulb test
(1) Distinguishing method
a. Visually check whether the electrodes at both ends of the bulb have been seriously worn out.
b. Visually check whether the ceramic tube is broken or damaged.
c. Check whether the visual line is broken.
d. Check whether the lamp tube is broken or damaged.
e. Check whether the lamp column is broken or damaged.
f. Check whether the lamp tube is loose or not.
g. Visually check whether the Base is loose or falling off.
h. Check whether the power cord of the bulb is loose or falling off.
i. Visually inspect the bulb for cracks or cracks.
(2) Test method
a. Take a good Ballast (ballast) as a benchmark for testing HID lamps.
b. Prepare a power supply and adjust its voltage to 13.20V as the test reference voltage.
c. Connect all wirings first, turn on the power and test whether the bulb will light up.
d. If the HID light cannot be turned on when the power is turned on, it means that the HID is damaged.
2. Ballast test
(1) Distinguishing method
a. Visual power Whether the cordset is damaged or damaged.
b. Check whether the visual control line group is damaged or damaged.
c. Check whether the high-voltage line group is damaged or damaged.
d. Visually check whether the high-voltage box wire group is damaged or damaged and leaking glue.
e. Check whether the ballast body is damaged or damaged or leaking glue.
(2) Test method
a. Take a good HID lamp as a benchmark for testing Ballast (ballast).
b. Prepare a power supply and adjust its voltage to 13.20V as the test reference voltage.
c. Connect all wirings first, turn on the power and test whether the bulb will light up.
d. If the HID light cannot be turned on when the power is turned on, it means that the Ballast is damaged.
e. If the HID light can be turned on when the power is turned on, it means that the Ballast can light up, but it is necessary to check the input current of the power supply to judge whether the function of the ballast is normal.
The judgment criteria are as follows:
The normal input current range is between 3A-5A.
Greater than 5A means that the ballast work efficiency is reduced, resulting in increased power consumption and reduced reliability.
Less than 3A means the ballast’s working efficiency and reliability are reduced, which may lead to the situation where the light turns off and then turns on again.
