Light from a electric bulb is generated when the negative & positive prongs inside generate a spark upon touching creating light.
How do you unlock a 2005 Chevy Tahoe with keys locked inside?
Don't they come with "ON Star" for the first year? Otherwise, call the local police department. They often carry the tools necessary to get into a locked vehicle. If that doesn't work, call a locksmith.
Call AAA, or other automobile club or lockout service.
What does the dashboard symbol mean that looks like a water can but not a gas can?
That symbol usually indicates a low windshield washer fluid level. It's a reminder to refill the reservoir with water and washer fluid mixture to maintain a clear and clean windshield.
The word "sustainable" is used in environmental and energy circles to refer to sources of power that will not run out. With that definition, solar power is considered sustainable because we presume the sun will always shine.
Wind and water are other sources of sustainable power.
What can cause the turn signals and brake lights to stop working if the fuses are okay?
There could be many things causing that problem. Here are some suggestions:
Since the brake sights go through the turn signal switch, something is causing the ts switch not to receive any voltage. You just have to trace the wires and find out what happened. It could be the ts switch itself.
I had the same problem on my 98 Grand Marquis. I fixed the problem by spraying WD 40 around the hazard hazard flasher switch, located on top of the steering column. This is a multi-function switch that contols turn signals, brake lights, and flashers. After spraying, I pushed it down with my thumb and let it pop up several times and also wiggled it around a bit. It worked for me - problem solved. Apparently, over the years gunk finds it way in there, be it dirt, liquids, etc.
Responses to the WD-40 advice:
Cleaned my Jeep Wrangler 2000 yesterday and when I started to drive to work this a.m. someone waved at me from their car and informed me that my brake lights were not working. I then noticed that my turn signals and hazards were not working either. First thing that came to mind was that the poor Jeep was in shock from its yearly cleaning...I stopped at a gas station but attendant was clueless. Came home and found the post about the WD40 - this only after having read others about green and white wires and brake switches which I wouldn't recognize even if they danced a jig for me but that I did crawl around and look for anyhow. After reading the WD40 post I snatched my trusty WD40 from under the sink, ran to the patient (Jeep) - sprayed, jiggled, sprayed, jiggled and lo and behold I have hazards, turn signals and brake lights again !! WD40 is my very best friend and to the guy who posted the advice to use it.
Noticed my brake and turning lights weren't working and after looking through the fuses and wires tried the WD40 trick. Worked like a charm!
I am shocked, but the WD40 trick worked for me too! I spent about 4 hours tring to fix the 'short' in my 1999 Jeep Wrangler, and almost gave up. Thanks to everyone who posted answers to this incredibly frustrating problem!!
That Is wild, I bought a 1998 E150 high top Conversion van, so I tried everything out, not to mention trying things I rarely use like 4 ways, well I noticed last night my Turn and Brake signals were out, So this Morning In the Rain I started working on it, so I did the fuse thing, I traced the wires for the Alarm system, and Still nothing, Then I got to wondering since I have not bought a manual for it, so decided to look online running back and forth in the rain to my computer trying different things and came upon this Post and I didn't have WD-40 but I did have PB blaster and I sprayed a little along the side of my 4way button and Boom everything works again... Wow Im really happy but wet that I found this post .. Great trick

Thanks for your help, Rickgmi. Recently my left brake lamp on my 93 jeep yj became intermittent. Also, I noticed the left turn signal did not usually work right either. I did not connect the two, and proceeded to try to find a short in the wiring to the brake lamp.. I made it from the brake lamp assembly to the harness under the dash, to no avail. Frustrated, I went online and found your post. I sprayed WD40 as best I could on the interior of the hazard light switch, and the turn signal switch assembly. I had my brake light hanging over the back door (working by myself) to see it from the driver seat, and things were all messed up. I remembered that the lamp assemble must bee grounded to the body/frame to work correctly, as it does not have a dedicated ground wire. I immediately re-attached the lamp assembly, and WHALAH!! Your fix worked like magic. I really appreciate you taking your time to post this fix. It saved me hours of frustration and $$$!
Where is the negative coil wire and where is the coil?
its part of your distributor cap. hope this might help.
1200 watt max is the RMS watt half of the max?
NO! The maximum power rating of some amplifiers can be five or ten TIMES the RMS, or continuous, power output the amp is capable of. This problem is far worse from low quality imported amplifiers than from more reputable higher quality ones. Always look for the CEA power rating on the box, if it is available. This is a government regulated program which ensures the consumer is aware of actual amplifier performance.
How do you replace the rear turn signal lamp on a 2001 Buick Lesabre?
This is also documented in the owners manual. Open the trunk and remove the side-carpet retainer clips, these push-on, but need to be unscrewed to be removed. Once the clips have been removed, pull the side-carpet away, this will reveal the bolts holding the light housing. The nuts are 10mm, remove them and then push on the studs/bolts to push the light housing free. You can now access the light bulbs. Experience has shown that if one goes bad the others will follow shortly, so replace the bigger lamps and the smaller ones at the same time.
You would normally find it under the dash near the steering column. It is not in the fuse panel. It's left of the ashtray. Turn on the hazards and listen, the turn signal and 4 way flashers are side by side. You don't say what kind of vehicle you have, but if you are looking for a stand-alone flasher unit on late model Ford, Mercury, and Lincoln vehicles, you won't find it. It is incorporated within the hazard flasher swith, located on top of the steering column. This is a multi-function switch that controls turn signals, brake lights, and emergency flashers. If these lights are not working, a quick fix is to spray WD 40 around the switch. Then push it down with your thumb and let it pop up several times and also wiggle it around a bit.
How do you change the map light on a Kia Sedona?
The entire overhead console unit clips into a socket. The entire overhead console unit must be pulled down from the ceiling of the car. There is a single phillips-head screw towards the windshield that attaches the console to the ceiling. Once this screw is removed, use a small pry bar to pull down on the console on the opposite end. The console is held in with two or more metal clips that will disengage when you pull down with the pry bar. When I did this the other week, I was afraid I would break the console by pulling too hard, but it un-clipped an came right down. You will see the light bulbs clipped into the sockets. The sockets must be retracted from the console, then the light bulbs can be replaced. Do not squeeze the bulbs too forcefully, or they may shatter between your fingers!! Installation is the reverse of the above procedure.
Adjust or replace the back up light switch, located somewhere next to the shift lever.
How do you wire a dual voice coil to an amp?
If you want to run both coils,you have to wire the positive to positive and negative to negative on your sub,then run a wire from each plug to the amp. Positive to the positive side of the amp and negative to negative side of the amp,(you can run in bridge mode or stereo if your amp can handle the load)
If service light is on and the air bag fault light is on what is the problem?
You will have to have the system checked for codes to know possible problems.
Which unit is used to describe electrical pressure?
The unit of measure used to describe electrical "pressure" is the "Volt."
Zero. Watts is the product of Amps x Volts. As you can see an amperage value is needed. Voltage = Watts/Amps. Volts = 200/? 20 volts
a motor is powered by electricity in the motor you have winds of wire that take an electric charge,this is dischached thru a magnet. this in turn creates a feild which drives the stater and makes the motor spin that is how a motor works an engine however works on pistons compressing a liquid enuff to turn it into gas which is then ignited by a spark plug in a gasoline engine, or purely by compression in a diesel engine the burning of the fuel creates pressure which in turn forces the piston down ,which turns the crankshaft,which turns the drive train
It starts out with 480 Volts, which is used to power motors. 480 can be stepped down to 120/208/277. The 120 operates normal appliances, while 208 can be used for dryers and welders rated for 208. 277V is usually used for lighting circuits. 3-Phase is used in commercial and industrial settings.
Where is the MAF and ECT located?
The MAF is located on the intake side of the engine, usually between the airfilter and the throttle body. The ECT (Engine coolant temp sensor) is usually located on the side of the engine block.
Is the tape player wiring plug the same as a CD tape player wiring plugfor a 97 Subaru Legacy?
Yes. Its only an audio output. If you want pin outs, do a search in Nasioc.com under Impreza stereos. I can't remember the exact link. Have fun Osei
Why does the fuse for my dash board and tail lights blow on my 1996 Chevy pick up?
Fuses are installed to prevent damage to parts that are electrically downstream. There may be a short in your wiring causing the fuses to go. Until you find the short you will keep blowing fuses. Check the resistance between the fuse and the device with an ohmeter if you can. To do this;
1.disconnect your battery
2.remove your dash instrument cluster
3.check wiring diagram in your shop manual to check wich wire supplies power to it
4.unplug the connector
5.then check the resistance from the side of the fuse holder that goes to the cluster with the power wire at the connector. It should be zero or very low.
If it isn't you probably have a short in the wire. If it is you may have a problem with the wiring in the cluster.
You can also get under your dash and physically examine the wiring.
Why are electrical systems grounded?
Electrical systems must be grounded for the devices to function. The flow of electrons that drive them are attracted to the opposite pole of the battery and will not go through an electrical device that doesn't allow them to get to that pole.
My 2001 Dodge also has a fuse box on the end of the dashboard (drivers side)
