SOURCE: 89 Thunderbird, no tail lights

There are 3 wires behind the headlight switch brown+, brown-, and white. All 3 wires are normally clamped together.

I'm not sure what the white does, but when the two brown wires are connected, your parking lights work like they should.
If the brown wire leading from the bundle of cables grounds to the metal switch mount, it will blow your fuse.

If your parking lights don't work, and your rear lights don't come on with the low headlights, these 3 wires could have come undone.

SOURCE: tailight fuse blows when headlights are turned on

Hello my name is Ben. I know you checked the wires, but I'm thinking you missed something. Try unplugging one of the headlights and see if the fuse blows, if it does plug that back in and unplug the other one. This may give you a place to look for a problem in the wires.

Headlight wiring diagram

Honestly, there simply not much difficulty to the way headlights are wired on any vehicle. Standard headlights receive positive 12v from the headlight switch directly (or through a relay, if you have automatic headlights), and the switch receives power through the fuse block from the battery. When you turn the headlight switch on, you should get 12v at the input connector to your headlights. If the headlight connector is not receiving +12v at the connector when you turn the headlight switch on, check the fuse, the switch, and the relay. If the headlight assembly is receiving +12v at the connector, check the bulb. If the bulb tests good with an ohmmeter, check for a broken ground wire. That is simply all there is.

Kia sedona 2002, ABS light always blink for about a second or two almost every day and shortly after my headlights burns out. Please, can someone help me out? I am tired of buying bubs.

It is possible that your alternator is overcharging/sending too much electricity to the headlights, the headlights are most likely on a different circuit than the other electrical circuits. Usually they have there own circuit because they use so much power, There is usually a relay circuit that works (like a solenoid) which connects the larger wire together. Also if the relay or solenoid is bad then maybe the lights are flipping on and off and it blows the blubs. Also it is possible that you have a short in the wiring which goes to the bulbs which causes power fluxuations which blows the bulbs. Are you sure the bulbs actually burn out? Or do you replace them in the daytime after they burnout or go off at night driving. You also have a Circuit breaker which can cut the lights off, then perhaps after the car shuts off and cools down a few hours it resets and works again, again this would be a sign of a short OR your using the wrong size or wattage bulbs which takes more electric than normal for the circuit breaker.

Driving lights and dash lights blowing 15 amp fuse

From your description this looks like overcharging. Check your charging system for overcharging and the wiring. A loose connection to the regulator can cause a surge in charge voltage and let out a very high voltage.

2004 sprinter headlights keep blowing out

Hi, what voltage is the alternator putting out? Put a voltmeter across the battery - it should be reading between 13.8 to 14.4volts. Any more than this and the regulator unit on the alternator is likely to be faulty. Normally a cheap fix

98 Nissan maxima. Both headlights went out. Fuses seem to be good. What do I do?

To make it as simple as possible, you only need a (+ 12 volts) positive wire and a (- ground) to make any electrical circuit work. I would guess you have lost your power and the first suspect is the fuse. It is sometimes difficult to look at a fuse and determine its integrity. I would swap in a new fuse first. It is possible to have had both bulbs blow and if you have a test light or meter you can check power at the headlight receptacle. Depending on your expertise it boils down to basically you will have power at the light (bad bulbs ) or no power ( bad fuse or broken wire or headlight switch bad). Just remember when replacing fuses, it must be the correct amperage fuse. If its insufficient, it will immediately blow as soon as you turn on the headlights.
Hope this helps you some.

Hello all, help required please! The dipped headlamp bulbs keep blowing on my X Type Jaguar, 2.0 SE petrol 2003 model. I've been told that the wiring needs to be replaced to resolve. Ideally I would like...

This is not really a solution, but more like a thought.. If the wiring is bad.. you'd be more likely to be shorting out, blowing fuses.. Have you checked the voltage regulator? If it's spiking from time to time, could blow head lights, without necessarily blowing other things. Have you checked the headlight mounts. Vibration could cause them to go out offten. You did not say how often they blow ! Or if they go together or one at time. [One thing I noticed with high performance bulbs, they seem to last almost exactly one year. (Give or take a month )]

reasons bulbs keep blowning.your head light bulbs is halogen bulbs.dont touch with bare hands.the oils on your hands will make them over heat and use clean gloves on your hands when replacing the head light bulbs.if all is good.check alternator out could be overcharging causing too much current flow through electrical circuit blowing out bulbs.use a digital volt meter hook it battery with car running battery voltage should be 13.5 to 14.5 volts. if it is 15 to 16 volts too many volts.alternator is faulty.due to lock out features turn off radio before disconnecting battery cables so you wont lose radio playing code.

89 Thunderbird, no tail lights

Having the same issue somewhat. Tail lights and dash lights quit. Checked the headlight switch wiring harness by looping all other prong holes back to the main power and they all work, so mine must be the switch. Having a real hard time finding a switch that matches the old one, even though they say it is a replacement. I paid the $25 at and they have quite a few wiring diagrams for the car.
