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 strange because you would think the cable would not drop voltage but it sure can. If the battery post is dirty or bad connection, you could see a voltage drop all the way to the maximum 12 volts battery voltage depending upon the connection. Also you can check the return path the same way--- Negative case of the starter to the negative post on the battery for voltage drop. If it is more than a volt or two, you have a bad ground return circuit.

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 to the chassis of the vehicle. You apply 12v to one wire and get low and 12v to the other one for high speed.

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 be 13.8V; 0.5V higher or lower is the limit of what is acceptable. A voltage too high is NOT good: it will ruin your battery and wear out bulbs and other equipment!

A voltage regulator is good when the reading hardly reacts to change of engine speed or to adding power consumers like electric window heaters or main headlights.

Ans 2: sometims the voltage regulator is faulty when the remainder of the alternator is OK so it's worth considering replacing the regulator first because it is less expensive and sometimes it can be removed and replaced without taking the alternator off the car.

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.

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.

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 the circuit wire that is shorted and watch the needle fluctuate back and forth. when you pass the area of the short, the needle will stop moving. You have located the short where the needle stops moving. You can use the gauge near pillar posts and body metal also and it will sense the wire even through car metal. The objective is to find where the wire is shorted in the car body or location. Most shorts are found where the wires are EXPOSED and not inside pillar posts or body parts where you can't access the wire harness.

Interior light fuses are mostly rated for 10-15 amps.

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. ------------------------------------------------------------------------------------------------------------

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.

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 attached.

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 sources out in space.
