Car Electronics and Lights
Gauges, speakers, signal lights, headlamps and cabin lamps are all parts of a car’s electronic equipment. The majority of cars use a 12-volt power source, and include a fuse for protection from power surge.

What is a sample voltage problem and formula?
The formula for voltage is: E = I x R
(E is voltage measured in volts, I is current measured in amperes or amps, R is resistance measured in ohms).
Sample problem:
An Mp3 player has 40 ohms of resistance and 0.1 amps of current flowing through it. What is the voltage that supplies the Mp3 player?
Start with the formula, E = I x R.
Put the values given into the formula: E = 0.1 x 40
Now, do the math: E = 4 volts
How do you repair the wiper assembly on a 1996 Nissan Altima when only one wiper works?
Your problem is a broken linkage arm, that runs from the wiper motor, to the wper arm. This is located under the cowl. Look down into the grill under the lower edge of the windshield, and you will see the arm. This is NOT something that you should try to fix, yourself. You need a shop to do this repair for you.
Not necesary a bloken arm, could be a loose arm. There is an assembly part betwen two arms and it's a press-assembly so maybe its just a loose part. Let me guess, it's the driver side wiper, right?
....
i had that same problem in my 1996 Nissan altima. it happened to the driver side wiper.. what i did was i went under the hood and pulled up that rubber piece over the shield that keeps the leaves, etc, from getting into the car. then i undid the nuts that held the plastic piece down. then i saw that the metal had rusted and the end of the arm was no longer screwed on. i fixed it once with a ziptie but the arm cut through that after 2 weeks. then i went to home depot and bought a round metal thing that screws on to pipes to hold them together. i held the arm to a piece of metal above it and then i took a tube of grease (some sort of car grease that costed like 4$ or maybe less) and i squeezed it all in there to stop it from making a horrible scraping sound. it sounded bad for the first few days that i used my wipers but now it sounds fine and it works perfect. its a cheap 6$ fix. it only took about 15 minutes to do it.
How do you disable the daytime running lights on a 1998 Chevy prism?
try pulling the drl relay located inside the hood passenger by side headlights. Or pull the fuse to the relay. Good luck,
Type your answer here... 450000 hz
Why do batteries lose charge if placed on cement?
It actually is based upon temperature-----. Batteries are insulated in a plastic or rubber case, so electricity leaking to the cement is not in the question. Even more so, batteries normally sit in a metal tray in a car. If battery leakage were to occur, it surely would sitting on metal.
The actual cause is temperature difference between the top of the battery and the bottom. The specific gravity of the electrolyte changes with temperature. Therefore the specific gravity of the electrolyte is less at the top of the cell and more at the bottom. As measuring the specific gravity tells the state of charge of the cell, the cell has more of a charge at the top of the cell than the bottom. This causes an internal current drain inside the plastic battery case.
All batteries will discharge no matter where they are sitting when not being used. This is called "Shelf Life". A battery will not be damaged by sitting on a concrete floor versus sitting on wood. You will just have to charge it up to use it. It should be noted that a lead acid battery will eventually sulfate the longer it is discharged. Sulfation is not fully reversible.
People who believe that a battery is ruined by sitting on a concrete floor don't realize that probably the battery was acting up to begin with and was removed from a vehicle because it was going bad. After sitting on a concrete floor for a period of time, they try to charge the battery and find it bad. Therefore the conclusion was that the concrete floor ruined the battery instead of the battery getting plain worn out from usage in a vehicle.
It is all due to temperature and nothing else.
Where is all the relays on a 1998mercedes e430?
Most relays and fuses i have seen in mercedes' were under the hood on the driver's side.
Is there continuity from the center lead of the feed line to the antenna rod on a K30 CB antenna?
There will be some amount of continuity in a k30. There is a coil at the bottom of the antenna base, so the ohm reading will be high, but should still be there.
Where is the horn relay on the 2007 Tahoe?
The horn relay is located in the fuse box under the hood of the 2007 Chevy Tahoe. The horn relay is responsible for making the car horn have sound.
What does error 3 mean on a Mitsubishi Montero CD player?
Error code 3 on a Mitsubishi CD player means that the track is out of line. It is possible that a CD broke inside the player that caused the track to jam up. Either way, the CD player will have to be replaced.
What is the wiring colors for a earthquake PA - 2075 AMP?
Earth Quake:
Red is L+, Purple is L-, White is R+, Brown is R- , Orange is Remote
Why you use tetrode instead of triode?
a tetrode is used when you need a screen grid tube, but a suppressor grid tube can't be used.
OK, but the question was "why use a tetrode instead of a triode?"
So, the answer...
1. A tetrode has a higher voltage/power gain than a triode.
2. A tetrode has less anode-grid feedback capacitance than a triode, and can operate in common-cathode radio frequency circuits without the neutralisation (or other corrective circuitry) that is needed by a triode.
Explain step by step how to put in the blower resitor?
Remove the electrical connector from the old resistor. Remove the screws holding the resistor in place. Remove the old resistor. Put in the new one and screw in the screws. Attach the electrical connector.
Can you put kicker subs in a car without a amp?
Yes and no,
Subs could theoretically be hooked directly to the speaker output of your headunit using standard speaker wire and connections however this would be the equivalent of using a fly swatter to kill a bull. With out the power of an Amp (slang of amplifier) you are defeating the purpose of adding subs (slang for sub woofers) to your pimped out ride. If you are adding the woofers to get that Booming, wake up the neighbors, annoy the entire community sound you need to add the amplifier other wise you will just have really big speakers. The power of a typical head head unit is only 50 watts per channel. The average 10 inch sub woofer requires at least 200 watts to operate at its optimum efficiency. Save your lunch money for a few months and buy an amplifier. Then buy a Capacitor. Then buy some better sub woofers, don't waste your money on those neon lights, they'll get broken the first time you have to get tires put on your car.
This more than likely has nothing to do with the turn signal switch. Check the bulbs, fuse, and look for loose wiring.
Actually, I had a similar problem on my 97 Lumina and it was the turn signal switch. I'm getting it repaired tomorrow so I'm not sure what it costs yet.
What can be done if halo lights stop working?
It's hard to imagine both lights going out at the same time unless they carry a common ground because they are usually powered seperately. Exactly what kind of vehicle is it, that possibly I can look for a wiring diagram.
Can the need for an alignment cause a car's brake warning lights to NOT go off when they should be?
The brake lights are usually operated from an operating switch off the brake mechanism. It is most often a switch on or near the pedal, though a number of variations are also found. The switch has some kind of adjustment so that it will be activated and deactivated at the "right" time when the pedal is depressed and released. When the pedal is pushed down, the brake light circuit is powered up (through the turn signals, of course). When the brake pedal is released, the switch is opened and the brake lights should go off.
If the brake lights do not go off, it has nothing to do with the wheels or any alignment issues. This is an electrical problem, and it centers on the operating switch and associated circuits. Remember that the brake lights are not an "isolated circuit" but work through the turn signals and flashers. Look at the brake light switch and how it is set up and adjusted. If this is all good, then look through the rest of the electrical system for the cause of the problem.
How does ignition control unit operate?
a control unit works by this other thing that makes it work but it also saves things.
