You don't mention what type vehicle your working on, but I assume it has HID lighting. Have you gotten a good ballast? Cheapest fix would be to find a similar car in salvage yard and swap parts until you find the issue. Then buy new parts.

Why my car when i turn large light fail and the car try to turn off?

I also agree with electrical power failure. Either the battery or the alternator is not charging enough current.

check the voltage supply of your alternator, it must be supplying more than 12v and less than 14V.

What happens when you hook a care battery up backwards?

Hello Glen, Bad bad things can happen when you hook up a car battery backwards. If your car has a high quality electrical system it might only blow out one or two main fuses. If not, it can cause havoc on the wiring system and burn out the alternator, computer, sensors, modules, and stereo system to name a few.

Everything is on but no sounds from starter when trying to start it up.was driving it the same day no problem

If all the electrical accessories are getting power, then the problem would be in the starting system. First check your positive battery cable. There will be two large wires connected to it. One goes to the fuse box and accessories and the other to the starter. It is possible that the starter one is not getting good contact. Make sure that there is 12+ volts going to the large wire at the starter solenoid. If so check the small wire that goes to the solenoid. With the key in crank mode there should be almost 12 volts to it. If you have both 12 v at the large wire(all the time) and 12 v at the small wire when the key is in the crank position you have a bad starter. Try hitting the starter while someone is holding the key in the crank (start)position. If not check for fuse or relay labeled starter. Also check the neutral safety switch to see if starter voltage is passing through it when the lever is in park or neutral.

I keep blowing my PCM BAT fuse in my Lumina

you need to find the wire or component that is giving feedback into that system and then you can fix it. Putting a LARGER FUSE is only taking away the security of the system

How do you replace the seat filter in a 2004 lincoln navigator

If you are having problems with the HID head lights it is probably the ballast and is located on the bottom of each light. New it cost $275 but can be found on e-bay used for about $100. The bulb cost about $110. Be careful with bulb as you cannot touch the glass part. Oil from your hand will cause it to explode when it gets hot. I was told it was bulb. Then I was told it was light switch. Then they told me it was fuse box and would cost about $3,000 to replace. I found out it had ballast and they are not part of the bulb like the auto part store said. Took ballast from left side and put it on right side and light worked. I spent a total of $500 to fix a $100 problem. Ballast are good for only 3,000 hours so you take a chance buying one that is used.

While trying to tighten the alternator I hit the 'hot lead' accidentally with my metal ratchet which caused a loud snap and blue flash where the hot lead attaches to the alternator. Since then, the car...

Look in your fuse box and see if you see a fuse labeled alternator. It may be marked "ALT". Try to locates that. The alternator is all electrical. There is a chance it is shot if it took a good impact. Locate it, try it, and write me back.

Emission test coe PO455

The missing ABS fuse will not set this code as ABS is not part of the emissions system. This code is caused by a leak in the EVAP system. Replacing the fuel cap is probably the cheapest solution if you're lucky. Very rarely will the cap be bad. You'll need to check the entire EVAP system for leaks, loose connections, bad hoses etc. The main problem that will trip this code is the EVAP control solenoid. If after checking the system you find no bad hoses or other obvious leaks you'll need to replace the EVAP solenoid.

The solenoid is located under the car behind the fuel tank on the rear cross member. It looks like a little black boc with an electrical connector and two hoses coming from it. Good luck.

Fuse good told that brake electric wire bad. what

There is a "Switch" that is pressed by your Breaking foot lever of most vehicles. Grab a flashlight and look for it, Turn the key on and see if you get any voltage to this switch. If you do get voltage to this switch, have someone watch the break lights while you jump the 2 wires. If you have power to it and jump it but still no lights, You must replace the faulty wiring.
