Can You Repair An Hid Ballast?

Symtoms of a bad HID xenon headlight ballast

High Intensity Discharge lamps, – HID – , also known in the automotive industry as Xenon HID lamps, need a device called ballast in society to work. The ballast is in accuse of converting  the vehicle's 12 Volts battery voltage to the incredible corporeality of between 18,000 and 30,000 Volts that a HID lamp requires to be lit up.Some systems practise this with an igniter unit, while others accept a built-in igniter.Another function of a ballast is to help the lamps to kickoff up quickly.HID ballasts work as DC to AC converters, since the Xenon bulbs piece of work with AC current while the car battery feeds them with DC current.Anchor reduces the output voltage, one time the lamp is lit, to about 120 or 110 Volts.

Then it keeps the output tension and voltage steady. A ballast has to work without causing the light bulbs to overheat; the Xenon gas inside the bulb has to be cool before receiving the high voltage current from the ballast. If  a lamp needs to exist turned off and of a sudden back on, the ballast has a built-in circuit to assist the lamps to exist switched on and off quickly without causing them any harm.

When you own a car with HID headlamps, whether it´s standard equipped or has been retrofitted, you are going to have a ballast controlling each Xenon bulb on your auto. If you are experiencing issues with your Xenon lights, have checked your bulbs and they are fine, and so you have a problem with the ballast controlling that bulb.

Bad Headlight Ballast Symptoms

Since Hid Xenon lights and ballasts depend on each other to piece of work properly, sometimes it is hard to make up one's mind whether the problem is in the ballast or in the bulb. Unless the bulb shows damage when you are inspecting it, (it's very easy to see when a xenon bulb is burnt), you will have to brand some experiments to encounter what's the real problem.
If the headlights are dim, changing colors, flickering, or if you hear a buzzing sound, information technology'south quite  possible that your anchor is bad.

Some other symptom of a ballast problem could be if your lights suddenly terminate working after some fourth dimension of driving the car, so, after some time, when y'all switch the ignition and lights back on, your lights start working again. This happens a lot with aftermarket HID Xenon Light retrofits. Sometimes the ballasts were installed nigh a hot surface, and the ballast enters in "safe mode", so information technology shuts down to avoid being damaged. When the ballasts cool down, they start to work fine again.

How to check and examination a headlight ballast

Ballasts tend to neglect because of time, heat and wet. When a ballast overheats or i's operating under very low temperatures, it is prone to fail, like any other electronic device..Y'all should check for wet getting inside the headlamps and for condensation over the inner wall of the headlight'due south lens. The combination of heat and humidity can cause corrosion over time. If yous are suspecting that a anchor is defective, you should cheque advisedly for any signs of corrosion and moisture in its housing and connectors.When yous are inspecting your ballast, you should too check for whatsoever burn marks and damaged casings. Ballasts are sensitive to shocks as well.

Some other easy test that you tin run, assuming that all the connections and fuses are working fine, is to supplant your headlights' bulbs- If the new bulbs don't lit up, so the anchor isn't working. Yous may take been unable to determine that your bulbs were defective in the first place.

If you take a multimeter, you can perform a resistance check. Connect 1 probe to the positive (red) wire of your ballast and the negative (blackness) wire of your ballast. If your ballast is bad, the reading volition exist "1", meaning that the circuit is open. If the reading is unlike from "1", you still take a hope, but you have to know the specific value of that ballast to be sure that it'southward in good shape.

With your headlights on, listen carefully for a high pitched buzzing racket, sometimes, you think that you are having a problem in one of your lamps, but the sound coming from one of your ballasts will show you lot where the problem is.

Conclusion

The ballasts are non user serviceable parts, they produce a very high voltage, and they are unsafe to handle. The all-time advice I could give y'all is to make sure that you have a defective ballast or lamp by swapping the lamps. Having both ballasts lacking at the same fourth dimension would exist very bad luck. So knowing what part needs to be inverse, I would only supervene upon information technology. It's wise to avoid tampering with a device that, once again, can be dangerous and could cause yous and your car serious damage.
