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.

How can we check the starter's external wiring circuit for volt drop?
For voltage drop checking on the wire from the battery positive post to the starter main terminal, you place the voltmeter reading on the 1 to 3 volt range, (or what lower range you have). You then place one voltmeter lead on the positive battery post, the other lead you place on the starter positive terminal and have someone crank the engine. While the engine is cranking, you observe the voltage drop. It should be less than a volt. This seems...
Why Wipers don't work on high?
Several possibilities are that: 1 the switch is bad on the high position. 2. There is a problem with the high speed wire from the switch to the motor. 3. The wiring inside of the wiper motor for the high speed is bad. The way 2 speed wiper motors work is there are separate windings inside the motor for low and high speeds. Usually 2 wires come out of the motor for low and high and the common ground through the wiper motor body...
How do you test a voltage regulator?
You just need an accurate voltage meter. Connect the meter to the poles of the battery. Start the engine and avoid spinning her up, even not for a short moment. The reading of the meter now can be anything; a reading lower than 12.6 volt indicates a weak battery. Slowly increase the engine speed. The meter reading should increase too, but will get "catched" at an engine speed somewhere at 1000 rpm. (8001200) From then on the reading will stay "locked". It should...

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...
55 watts is how many volts?
A Watt is a measure of power not voltage. Voltage X Amps = Watts (in a DC circuit) If you have a 55 watt light bulb for a car and you are looking for the amperage: 55W/13.8v = 3.99Amps (a typical alternator charging voltage is 13.8v) ...

What does the Brake Lamp mean if lite up?
It probably means that there is a problem with the electrical connection between the brake ligts and the brake pad and so it does not light when one brakes. Another possibility is that there could be a real serious defect in the braking system e.g. the brake fluid tubes. Answer It means a lot of things, but the most common and simplest is that one of the brake light bulbs burned out. Honda puts two in each brake light so you don't get...
What would cause your reverse lights not to work?
A blown fuse, a faulty ( or dirty ) reverse light switch, faulty wiring, a blown bulb or a poor ground could cause reverse lights not to work. If one light doesn't work it's likely to be a blown bulb, faulty wiring or a poor ground. If both don't work it's probably a blown fuse, a faulty reverse light switch or faulty wiring. ...
How do you dignose the interior light fuse keeps blowing out and what is the amp for that fuse?
Easiest way is to get a "short finder kit" This consists of a automatic reset circuit breaker to install in place of the fuse, and a small magnetic amp gauge that you hold in your hand. You can get these at a automotive store or a tool guy such as snap-on or a Mac dealer. You install the circuit breaker and it will click on and off about 1-4 times a second while short occurs. You hold the amp gauge near...
Where is the turn signal flasher on a 1993 Chevy Lumina 4 Door Sedan?
If it is like a Pontiac transport minivav , it is way up high ,under the dash, towards the center (left of the steering column) (A stupid place for it) Answer I have a transport minivan so I was happy to see the answer as to where the flasher is located. My question is, how do I get to it? Answer I HAVE A 93 APV AND THE FLASTER IS BY THE PASSENGER SIDE UNDER THE GLOVE COMPARTMENTREMOVE THE SCREW HOLDING THE COVER...

Why 2001 impala airbag light?
There are many reasons that the AIRBAG light come come on. The computer will need to be scanned to get the troubles codes. Trouble codes assist in diagnosis of what circuit has a problem. I would suggest getting that done as soon as possible, because an AIBAG light on may mean that the airbags will not deploy in a collision. ------------------------------------------------------------------------------------------------------------ ...
How many kilo volt amp equal 1 kilo volt?
Kilovoltamperes, KVA's, are a measure of electrical power, in kilojoules per second (real), while kilovolts, KV's, are a measure of electrical potential difference, in kilojoules per coulomb. The two units are not directly convertible without also knowing the resistance value or the reactance value and the power factor. Please restate the question. ...
What are the OBD-II pins?
Honda Man's Since we don't know what make, model or year your car is, this is a difficult question. If it is in fact OBD II, the connector should be located under the driver's side dash. In order to find your codes, you don't need to plug into the obd2 port. On the bottom right side of the diagnostic port, there should be two pins rather close together. My recommendation is to go to Auto Zone. Some of their stores actually have...
What is a tachometer generator?
Tachometers are instruments which are used to determing the speed at which something is turning [usually measured/indicated in Revolutions per minute]. There are many different tachs that accomplish this in several different ways. The tach that uses a "generator" is basically a voltmeter for the "read out," and a generator that creates a small electrical output which when supplied to [and properly calibrated to] the read out voltmeter guage, gives an indication of the Rpm of the shaft to which the generator is...
Problems with infrared telescope technology?
There are a few problems with infrared telescope technology such as, infrared wavelengths are absorbed by water vapor in earth's atmosphere and infrared telescopes must be kept cool. Astronomers have to place infrared telescopes on high mountains above the clouds so that the wavelengths aren't absorbed by the water vapor. Since infrared energy is heat energy, it's hard to keep the telescopes cool. If an infrared telescope is not kept cool it may detect itself and won't pick up on weak infrared...

How do you hook up a 1 farad capacitor to your amp?
A FARAD IS HUGE TO BEGIN WITH connect to amp? what an amplifier, output input?: people answer this question with no idea of what is the question . Answer 1 You first have to determine which side of the cap is positive and which side is negative. You run a wire from the negative side to the chassis and for the positive side you run a cable from the battery to the terminal and from the terminal to the amp. so that the...
