Fuses Meter
 Is there a way to check and see if a circuit board is still working with a volt meter? Ants got into my fuse box at my pool and now most of the electric equipment does not work. I tested the connections to the individual components and they seem to have power. My question is: is there a way to test a circuit board to see if its fried or not with a volt meter? It may not be enough to see that you have power - you may have to be certain you have the correct voltage coming in. If, on the other hand, you have power coming in and no power beyond a specific point resulting in no power coming out at all. It can be assumed there is a single point that is the problem. That point may be a fuse on the board, or it could be its own power supply / power converter ( transfomer). Test the resistance first You'll need to read the bands of the resistor to find its rating and tollerance - then check and see if that is where it is. Capacitators have numbers on them to represent its value and tollerance ...Inductors are harder ... they need to be tested with an inductance meter. Also remember, when testing resistance of a series circuit passive component you can test directly without removing component leads. I would do things in an orderly fashion. Now go back and test voltages of those components in order .. resistors then capacitators. Next, transistors (watch the probes [NPN or PNP transistor]) |

HID xenon conversion kits trouble shootings and solution
HID installation trouble shooting and solution
1. Questions: The HID kit work normally after installation, but the instrument panel display “warning”.
(For example: Audi A4 1.8T, 06 BMW, near Sagitar, Mai Tang, Rui-ming, Fox, near Volvo, Peugeot 206, etc.)
Principle: The original car is 50W to 60W, but the HID kit is 35W, some luxury cars have the On-Board PC Diagnostics system (EOBD System), and the EOBD will detect the "power does not match", So bring on the “warning” or radiation interference when light turn on.
Solutions:
- Using the special relay harness with resistance (25W) can solve the problem, 25W+35W,it is just 60W, the power match with the cars, then the kit will pass the EOBD check.
- Replacing the 50W bulb and 50W ballast, it also can solve the problem.
- Using special ballast;
- install the anti-jamming device
2. Questions: After installation, the car PC panel damaged by the electromagnetism interfere circuit.
For example: Buick LaCrosse, Buick Lu respect, the modern Royal Cheung Premium, coupe, Grand Cherokee
Principle: The car use a special electronic circuit board, it is susceptible to interfere, After install HID kit, the circuit board easy damage or light “flicker” or go out.
Solutions:
- It is solved by the special ballast with the Dedicated circuit configuration.
- install the anti-jamming device
3. Questions: after installation the bulb will appear the hard flashing, or often off, or the two bulbs not bright at the same time and so on.
For example: 06 BMW X5, 3251,5201, Mercedes-Benz S350, S500, Land Rover, BMW 3 Series, etc.
Solutions:
- Show headlamps current line of work are normal.
- Adding install the special decoder which solve the hard flash and lacking of current. Has been successfully resolved the case:
A, Ford B, Skoda C, the general public from Yu D, Sagitar E, Mai Tang
3. Show headlamps line whether there is traffic through the computer, if passing ,decoders needed to be dedicated in order to return to normal. (The company Mercedes-Benz, BMW and other special decoder)
4. Questions: Because of H4 H/L is the light need match with dozens of headlamps assembly, the difference of lampshade will make the difference focus effect, so it is possible that the low beam or high beam will astigmatism after installation, please communicate with driver and tell the turth.
Such as:1. Polaris own the bad focus, it is suggest that replacing the assembly or special Polaris H/L from the factory.
- Hyundai Tucson, it must use the special H/L which own the shortest base.
- Old GL8, Mitsubishi, Pajero, Swifts, Blue bird all being astigmatism, must use special H4 H/L bulb.
5. Questions: The light detect circuit of 07 and 08 S350 MBZ,BMW 5 classic and 7 classic are the lasted kits, it would be better to install the special 50w bulbs and anti-interference ballast.
6. Questions: After installed the hid system ,when turn on the auto radio, there have the single interference problem while the lights in on.
Principle:the frequency singles in the hid ballast and auto radio are incompatible .Sometimes the direction of the installed ballast also can lead to this problem.
Solution: Change the ballast position or adjust the ballast install direction can resolve the problem in some condition. Only shielded the ballast can resolve the single interference problem.
7. Questions: Just installed the HID system and everything works out fine with system ,but lately, it cann’t change light between high beam and low beam. After checking ,found the high beam fuse was blown. But the problem still up after changed the fuse when turn on the light.
Principle: Short circuit
Solution :
Firstly, Check the circuit carefully see weather there is any coating broken , disconnected ,connection wiring covered by the plasters or not and connected in the right line or not ,then remove and install a new ballast ,test and see weather still consist in the short circuit. If all above is fine then change the factory harness.
8. Questions: Some car moldes’ high beam after turn on for 10s ,one is on and the other is off.
Principle : Well,it occurred because of low current .As HID ballast need 8.5A or so to get start(then clam down to 3.5A or so in 1 or 2 min.),but most car original headlight circuit current was designed between 5.5A and 6.5A ,this bring the low current so that only 1 set HID can get enough start current ,then the left 1 set is off .This situation would happened in some high-ends cars .
Solution :
- add 1 set reply circuit, get the current directly from the car battery.
- Check the connect between ballast 12v input end and socket see weather there is any loose .The connect loose can lead to HID light in a low current when the car is running and shaking ,when the car is uphill and down hill for example.
- HID light is High Intensity Discharge Lamp , The ballast have an increase of high pressure protection circuit ,when in the abnormal situation , the ballast works fine but this kind of problem still insisted .Please feel free to send back the ballast to us for check and test .
9. Questions: Just installed a H4 H/L moving kit , one work ,the other doesn’t work but can moving.
Principle :This could happen when the grand connect condition is not good , Bad plug wire or Power Input Plug and Play in the wrong way.
Solution :Change the plug to the anti way.
10, Questions: Hyundai Coupe, after installed HID kit, start up engine and turn on the light, the light will “flicker” or go out; But turn off the engine, then turn on the light, the light work normally.
Principle: After installed HID kit, the HID light can work normally when the engine turn off. Once start up the engine, the light will “flicker” or go out, the car gauges set’s displayed failure light at the same time. The reason is auto Headlamp control line need passed the “check” by car PC system, however the HID work principle and work power is different to Halogen lamp, so the “check” can’t get any signal of the HID kit, let’s the check failure.
Solution: Our company have design a specail Auto PC check relay harness, can be match with HID kit.
11, Questions: PASSAT, after installed the HID kit, the Auto CD audio will pause when change High beam and Low beam, why?
Priciple: The reason is the pulse-frequency which arise from start up the HID kit is same as car’s frequency, the pulse-frequency make the car receive wrong signal, bring on the CD audio is pause.
Solution: Our company was design a special ballast for the car electric PC system, the problem can be solve after install it.
12. Questions: the lamp stock of BUICK EXCELLE is too small to put the bulbs in. how can I solve this problem?
Solution: Just drill the lamp stock to a bigger one ( Note: pls drilling with your hands pill the drill out, in case the residual powder would caused unnecessary trouble.
13. Questions: Why the Low/high light can be lighted up but is unable to change reciprocally after I installed the Bi-xenon HID light on the Mazda M6?
Principle: this is resulted from faults in the electrical circuit.
Solution: firstly, check the circuit of the original headlights and the circuit of the input power of the ballast; if there is no problem with them. Then pls check out whether the fuse in harness and the car have been disabled by fusing. If all things go well, then pls just change the connector plugs, coz the connector plugs may be plugged-in in a wrong way
14. Questions: How to adapt the light?
Solution: Firstly, park the car evenly about 10 meters away from the wall with its head right towards it (tips: you can make a note to ensure the accurate distance)
Note: To adapt the light, the car should be under the normal load standard without any additional load.
2. Turn on the light, pls notice the aperture which was projected on the wall, that is the basis for adapting. The distance from the midpoint between the two lights to the front tread should be the same with the distance projected on the wall. Otherwise, the progress of adapting will have to be carried out according to the 3rd step;
The distance between the central point of the right light to the ground should be the same with the distance between the central point of the right light to the projected shape on the wall. While, the distance between the central point of the left light should be 10CM higher than the that.
3. adapting them in the same line. The light on the left should project straight forward, on the other hand, the light on the right can project to the right slightly. Coz it can brighten the road on the right hand and make you see more clearly especially it is foggy.
4. pls cover one of the light with a piece of thick cloth so as to adapt effectively according to the changes of the light beam projected from one of the light. To do this, you will have to prepare 2 screwdrivers (one for adapting the height of light beam, and the other one for adapting the width of it)
15. Questions: How to inspect the bulb be lighted up and what is the solution if it is unable to be lighten up?
Solution: The several reasons for why the bulbs can not be lighted up: the accumulator?ballast or bulb isn’t working anymore?the cable of power supplier or fuse is broken?imperfect connection with the power supplier? misconnecting with the poles of power supplier. According to these reasons, we can eliminate one by one.
- check whether the bulb is workable.
If it is the problem with the bulb, the bulb will let out noise when it is connected with power (sometimes, there will be electrical sparkle inside of the bulb). If the ballast doesn’t let out any noise, that means the problem doesn’t lies in the bulbs.
- check whether the ballast is workable.
start up the whole system with another ballast. If the bulb doesn’t light on, that means the ballast is unworkable.
- check whether the poles is misconnected.
Connect the poles the other way around, if the bulb still doesn’t light on, that means the problem doesn’t lies on this point.
- check whether the fuse is disabled due to fusing.
This inspection can be carried out directly with your eyes, or with the help of a universal electric meter after pulling the fuse down.
- check whether the accumulator is workable.
Replace another accumulator to see whether the bulb can light on. If the can not still, that means there is no problem with accumulator.
- if it is still unable to check out the key problem after all the steps mentioned above, pls check the hook-up wire. Make sure all of them is correctly connected without any looseness on the point of connection.
- change another hoop-up wire
