Depends AC or DC
CORRECTION!!! GEEZE!!! AUTOMOTIVE IS DC!!!
This isn't exactly an easy job but it is an easy method,,, you simply hook up an amp meter in series with your voltage source and your load. If you are looking to install an amp meter permanently follow the meters instructions, if you are doing diagnostic work ther are highend meters such as those made by Fluke that you can clamp onto the insulated positive battery cable that will read the current flow, you will need to follow the instructins that come with the meter for these as there are some variations.
BE ADVISED AUTOMOTIVE EQUIPMENT CAN DRAW A SUBSTANTIAL AMOUNT OF CURRENT! DO NOT USE A MULTI-METER THAT IS LIMITED TO 20 AMPS!!! Whilesome stuff is much lower in demand, many things in a car or truck can draw thirty amps and more... this can destroy a meter designed for a maximum of 20 amps.
ALSO the average automotive battery, is rated in COLD CRANKING AMPS, and this is not a true figure of how much amperage it can produce when fully charged at 65 degrees and above, at these temperatures these batteries can source more than two or three times its cold rating... THIS IS MORE THAN A LETHAL AMOUNT!

How far can you run a 12 gauge electrical wire?
This is a voltage drop question. To answer this question an amperage is needed.
How many amps does an arc welder draw?
Always check the nameplate on the device. It will have the serial no., how many hertz it operates at, the voltage, and amperage. Their are different types, so the amperage will differ as well.
Can you use 600 volt 14 ga wire on an electric dryer?
The maximum amperage that can be applied to a #14 wire is 15 amps. The 600 volts is just an insulation rating. Check the nameplate on the dryer to see what the amperage and voltage the manufacturer recommends. If the nameplate just states a wattage use the following formula to find the amperage. Amps = Watts/ Volts.
How many watts does a washing machine consume in an hour?
The same as it consumes in a second, or in a minute. Please note that a watt is a unit of power, not a unit of energy. Power means energy per time unit.To get the details, you can check the electrical specifications on your washing machine. Most such electrical devices have a metal plate with the electrical specifications written on it - perhaps on the device's back.
What does amps mean?
An amp is a mesurement of electrical CURRENT. There are milliamps,microamps,etc. Actually amp is short for ampere. An amp amp may be referring to the current draw of an amplifier also called an amp. A electronics dictionary does not have the term amp amp. It may be an invented term simply made up to impress the consumer or reader.
How do you check amperage draw on electrical devices 12v DC automotive?
connect an ampmeter in series between the power source and the device ex. remove the power + wire and fit the ampmeter between the + wire and the device alternitively you can get clamp on ampmeters they are dearer but you can test amps with out removing any wires they just clamp on over the wire and give you an amp reading
How do you check car alternators?
"Checking" Car AlternatorsIn my area [SE Texas] all of the national chain [Autozone, O'Reilly, and Advance for example] automotive parts stores have hand held portable test devices which they attach to my car in their parking lot. They do not charge for these services; they are free.These devices can check my alternator, battery, auto electrical system, and even the on-board computers.In the case of your alternator, these tests do more than just check for output voltage.
What is the check relay for?
automotive relays
Where can one find a car iPod?
The first place to look for any kind of automotive electronic device is at Crutchfield. They are one of the biggest sellers of these type devices. Also, check on Amazon.
My son shorted his lighter out and now there is no power in the fuse block for the door locks and the instrument panel Why wouldn't part of the automotive fuse block have power?
If it's not the fuses or electrical relays, the short-out probably damaged some wiring. Take it in for an electrical check.
What careers are available in the automotive field?
multiple fields are available in the automotive field. Decide what you enjoy doing, and more than likely the is something along those lines in the automotive field. Electrical, cooling, a/c and heating, power train(transmission, front and rear trans axles, four wheel drive applications,), tires and rims, auto body and painting, electrical, wind shields and rock chip repair, oil and fluids change, diagnostics, smog check and repair, even car washing! there are so many fields available in automotive. I may have missed a few.

How an amperage reading would be taken using a clamp-on?
Simply "clamp-on" the clamp of the amp meter to any electrical conductor supplying the equipment that you wish to check while it is in operation. It is better to use your clamp-on with each individual conductor one at a time.

If the battery is dead you will need a battery charger. If the battery is good and you have low amperage then you will need another alternator. Most parts stores will check it for you. If you are looking for MORE amperage then you would have to buy a larger amperage alternator.
