How do you check for amperage draw in a 12 volt car electrical system?

Place a current meter (rated for several hundred amps) in series with the battery. Or Place a large gauge wire of known resistance in series with your battery, use a high precision volt meter to measure the voltage drop across this piece of wire, then divide the measured voltage drop by the resistance of the wire. This will give you the current traveling through it.

What is Block diagram of electrical system?
a Block Diagram usually means that you draw the main components of a circuit/system with boxes *pretend / means in a box -/amplifier/-->/Analog to Digital Convertor/-->/Output/ a Block Diagram usually means that you draw the main components of a circuit/system with boxes *pretend / means in a box -/amplifier/-->/Analog to Digital Convertor/-->/Output/
Draw and label the human digestive system?
You draw the Stomach and the Intestines, the Esophagus, liver and pancreas
Why limit the amount of electricity passing trough a circuit?
Circuits are limited for a few reasons firstly because certain size wiring can only handle so much voltage and amperage before it could fail secondly wiring heats up when more amperage is drawn through it which can create fires or burning out of the circuit most appliances draw set amount of current and amperage if you have a low amperage appliance Eg pool pump drawing 4 amps and the windings start to fail the motor can start drawing excessive amperage creating a hazard, if you had a large circuit it may never trip the breaker indicating a fault with the appliance which can cause catastrophic failure.
How many amps does a cordless drill draw?
Full size drill can draw up to 20A. Depends on drill/battery/torque. You can wire inline fuse holder and step down fuse amperage until it blow. It won't be a peak but some averaged max current, see fuse characteristics.
How are windmills used in 1800s?
to draw up water from underground aquifers
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 using larger wire sizes reduce amp draw?
Larger wires will not reduce the amperage draw of a device. Limiting amperage draw is accomplished by fuses wich blow when the amperage drawn across them exceeds their specifications.
How is Amperage Draw determined in electrical devices?
Ohm's law revisited; Current (amperage) = voltage divided by resistance. E=I/R http://www.glenbrook.k12.il.us/gbssci/Phys/Class/circuits/u9l3c.html http://www.bcae1.com/ohmslaw.htm
What makes a marine battery's terminals hot?
Amperage draw, excessive amperage draw, and or dirty & loose connections. This should be checked out if the temperature is elevated when not cranking your engine.
How much amperage does a dishwasher draw?
Each electrical equipment draws a different amperage. Most residential dishwashers draw about six amps. There has to be a specification sticker on the inside of the door of the dishwasher ,which must such information stated on it. Commercial dishwashers could draw sixty amps and be using three phase power!!
How do you determine the equipment ground wire size for equipment?
It is an electrical code rule that is determined by the amount of current that a connected device draws. Depending on the amperage that the equipment will draw determines what the size of the wire needed to handle the fault current. The larger the amperage the larger the ground wire needed.
How can you check to see if a starter for 1998 Ford F-150 needs to be replaced?
Remove and bring to an auto parts store that is capable of checking it for amperage draw and load
Starter dragging on my ATV and now it want turn over OR SAY A WORD?
Check battery voltage Check battery cables Remove and test starter for drag and amperage draw Repair or replace starter
How to check an electrical system drawn through a circuit?
To check a draw on a circuit you need to decide a few things and think about you situation.What am I trying to do. I have an unexplained draw? I want to know how much this circuit is drawing while operating? Is it blowing fuses or cycling the breaker?What tools do I have available?Do I have a wiring diagram?If we have a draw on the system killing the battery and we have a test light. We can disconnect the battery and place the test light between the battery terminal and the cable. A draw of consequence should light the bulb dimly. Then we start removing fuses and checking the light until the offending circuit is found.If we have a ammeter we can determine what amperage is being drawn, what circuit is drawing and so on using basically the same techniques.To figure out what is wrong a wiring diagram is invaluable as it will be a map to tracing the circuit through the car.
How many amps does a 1.5 hp dc motor draw?
1 horsepower is equal to 0.7456 kWatts, therefore 1.1184 kWatts will be the power consumption of that motor. The current draw depends on the voltage, simply use the P=UxI or I=P/U formulas to figure out the current draw (P=1118.4 Watts). some voltages: 12Vdc draw 93.2Amps 24Vdc draws 46.6Amps 110Vdc draws 10.17Amps 230Vdc draws 4.86Amps
How many watts does a compact fluorescent bulb draw?
Look for an amperage on the ballast. Multiply this amperage by the connected line voltage. This will give you the wattage of the unit.
Can you run a motor of greater amperage draw with a motor of less amperage draw?
It looks like you are asking if a higher amperage motor can replace a lower amperage motor. It depends on what the amperage difference is. If the amperage is high enough to move the capacity of the wire out of its rated value then it should not be done.Remember motor conductors have to be rated at 125% of the motors nameplate amperage. As the amperage increases so does the HP and the motor's protection will also have to be increased or the motor will trip the lower overload protection settings.Also keep in mind that if the motor is three phase, running a motor with higher HP on a load that does not need the extra HP, it will lower the power factor of the supply distribution.
