Electrical Troubleshooting

Parent Category: Electrical Wiring
Electrical troubleshooting involves checking and resolving an electrical problem (such as when an electrical device stops working correctly). Common troubleshooting practices include checking if the power is on, the bulb has burnt out, or the breaker tripped.
it should work as long as the batteries are connected in series + to - what you would need to check is if the charger for the cart charges 24v or 8v if it is 8v you would need to get a 24v charger for it it would be possible to charge the batteries with a 12v charger but it would need to be hooked...
what are the notes "my heart will go on " on viiolin
ohms voltage Ac Dc power i think thats all i know sorry guys
kVA - Kilo Volt Ampere The calculation used to find kVA is P=I x E Where P is Power in Watts (W) I is the current in Amperes (A), and E is applied voltage in Volts (V) The result is divided by 1,000 to denote the k for kilo. As such a voltage of 120 with 10 amperes being drawn would equate to...
Bad ballast can cause this, if you are using T12 tubes , upgradethe ballast to a newer T8 ballast and use T8 tubes.
Either all these lights are fed from one live (+ve) wire and thathas broken or you have a bad earth wire (-ve) for all these lights;unless many wires have been damaged. Take a length of wire that cantake 30A and connect to the -ve side of battery and connectdirectly to the -ve side of each light and...
I would say that probably the fuse holder is loose, this would cause a voltage drop and result in heating of the fuse. Replace the fuse holder.
You should not have received any shock IF (a) the iron's earth wire was properly connected to the safety earth or ground pin in the plug at the end of the appliance's cord AND (b) if the socket outlet's earth or ground connector was actually connected to earth or ground. If the iron's earth or...
You're right to say that but ONLY (a) if the iron's earth wire was properly connected to the safety earth or ground pin in its plug AND (b) if the socket outlet's earth or ground connector was actually connected to earth or ground. If the iron's earth or ground wire was actually earthed/grounded...
The term killowat simply means 1000 watts. Watts are computed asvolts times amps. A load of one killowat used for one hour consumesone killowat hour of energy. That would be 60 killowat minutes,however that measurement is seldom used.
A switch becoming hot is not normal. The cause could be loose connections where the wires join the switches terminal points. This could be the cause of the heat being generated. Misalignment of the switch blades inside the switch can also cause the heat to appear. Another cause could be that the...
where is the ecm unit in a 1997 Chevy Malibu 3.1 6 cly
Take the oven to an appliance repair shop. It sounds like the door safety interlock has jammed the opening mechanism.
If a 200 mA power supply is used on a circuit needing 2 amp it would overload the power supply. Two amps equates to 2000 milliamps. Trying to pull 2000 milliamps from a device that is only capable of supplying 200 milliamps is not advisable. The excessive current draw would most likely burn the...
The maximum distance of a wire drop between a service pole and service connection is undefined, as it depends on many factors not included in the question. The information needed to actually compute such a distance includes, but it is not limited to, the service volts, the service Class (60, 100,...
Using a megger you check from either positive or nuetral to ground.The megger should read open (usually OL). It doesnt matter whichconnection you choose as long as one is ground. If the megger showsanything other than open the windings are bad.
Quite a bit of bad stuff can occur, simultaneously, when a person is electrocuted. The first is muscle energy depletion. When muscles are electrically stimulated they go into spasm and deplete the sugar reserves, making it impossible for the muscle to continue to function. When that occurs, it may...
Maybe because you have too many items or something , maybe , just maybe , SEAN BEAN hacked into your laptop and freezed it with his freeze / cold ray gun that he uses in lord of the rings !!
You get 3 of them and hook them up in series. Then you can connect them to the 36 V battery.
if it is a plasma the plasma tube is going out if its a normal or flatscreen have the bulb checked or changed
1. THE SWITCH IS BAD 2.THE SWITCH WAS RECENTLY REPLACED AND WIRED INCORRECTLY (POSSIBLE IF THERE ARE MULTIPLE CABLES IN BOX 3.THE CABLE IS SHORTED (UNLIKELY, BUT I'VE SEEN IT) 4.YOU'RE TURNING OFF THE WRONG SWITCH-HA
For alternator electrical circuit input voltage = output voltage + ( current * alternator_impedance ) alternator internal developed voltage ( in the above equation it is referred as input voltage ) is constant, since the speed of rotation and field is constant throughout the operation. ...
Electricity is one of the many forms of energy naturally occurring in the universe. Specifically, electricity is the flow of electrons through a conductor, like a wire. It comes from other forms of energy. In the case of a power plant it comes from burning of fuel, nuclear reactions, rays of...
There are many components in HVAC and all of them have various types. For example: (01) Compression equipment: Compressor: Reciprocationg, Rotory, Screw, Centrifugal etc. In absorption system the compressing system itself is different. (02) Expansion device: Thermostatic Expansion valve, High...
Broad question.... Never become the path to ground, If the electricity flows across your heart, little as .4 milli amps could stop your heart. If you know its hot or energized and you have to work it hot have someone there with you and make them aware of the hazard and what to do.... worse case...
Because there is electrical current running through the wires and connectors, each of which have resistance, thus dissipating some amount of power as heat. Under ordinary use, no appliance plug should get overly hot. If something is too hot to touch with your bare hands, something is wrong and it...
Verify that the correct connections to the GFI are correct. It sounds like the ground wire is not connected.
An open circuit is a situation when there is no electrical path from the positive terminal to the negative terminal (in case of DC) or from the live terminal to ground (in case of AC)
If the charger is a 12 volt DC machine, connect the leads to the two battery terminals that the load is taken from. Take care to note the polarity of the leads to the polarity of the battery terminals. There will be a short jumper cable between the two six volt batteries. The charger leads go on the...
A diode should show low resistance with the leads hooked one wayand show an open with the leads reversed
To answer this question a supply voltage must be stated. Also the wattage of the lamps is needed.
To answer the question the voltage of the motor is needed as the wires size is calculated from the FLA of the motor. power p= 1.73*v*I*cos(phy) (1)find = I ? (2)assume resistivity of cu, lengh of wire (3)assume voltage regulation % is (10%) (4)V.R.(10%)=(vs-vr)/vr (5)find vs from above ...
The circuit is wired wrong. Contact a qualified electrician to make the necessary repairs. You don't describe the problem well enough to troubleshoot. If there is a fuse involved and it blows you would have to replace the fuse before anything should turn on. If this circuit worked at one time and...
I would opt for the two twelve volt batteries in parallel. This configuration will give you the voltage that you need for the system to properly operate plus the endurance time that you can draw from the batteries will be doubled. The amp/hours capacity of batteries when in parallel are additive.
Nothing will happen if you dip the free ends of the wire in a glass of distilled water with a 9 volt of battery for a minute.
Google star delta motor connections. If a motor is wired in star-delta (Yd), it starts up with lots of torque and then switches over to delta for normal "running". This is because the start-up current per phase when delta connected is much larger than star.
The Star/Delta starter was probably the most commonly used reduced-voltage starter, but in a large number of applications, the performance achieved is less than ideal, and in some cases, the damage and interference is much worse than that caused by a Direct On Line starter. Electronic motor...
The main breaker will have marking indicating size of electrical service, or if it is a fuse system....the fuses will have current ratings. If it is a subpanel, it might not have a main breaker. In this case you would have to look in the panel that the feed is coming from and find the size of the...
The question is not relevant. 240 volts refers to the "potential", and amps refers to the current. Potential * current = watts, or energy. You can have 240 volts at 1 amp, which will result in 240 watts, or you can have 240 amps at 1 volt which would also result in 240 watts.
Bus bars themselves don't usually fail. Failures normally occur at a connection point, and is usually caused by the bolt or screw becoming loose, or by corrosion. The resulting resistance causes the connection point to become hot, and eventually fail. The most common method of detecting this...
Good question. There are a few simple answers. Most solders begin to become "plastic" at around 350 degrees Fahrenheit and melt at slightly higher temperatures than even that. If you are asking about a hot water heater: If you are operating your water heating system at that temperature the water...
You are supplied with certain amount of power. Your main breaker has also limit and it will trip if overloaded. Another point: all circuits are provided with standards and electrician is obligated to setup connection at 80%. Ex. If bedroom has 15amp breaker amount of outlets( lights and...
how to hookup 1998 grand am alternator .
In a properly operating appliance, there is no connection between any of its internal wiring and its chassis and/or its metal case, if there is one. As such, the earthing connection being improper will not affect the operation of the appliance. However, and this is critical , an improper...
The first thing that springs to mind is that the pole faces of the contactor are dirty. If the contactor is in a position where it can get weathered, it would probably be a rust built up. Dis assemble the contactor and emery cloth the pole faces until they are shiny again. A light wiping of oil will...
Just multiply. (Note, this assumes no phase difference.) The formula you are looking for is W = I x E. Watts = Amps x Volts.
See related links below for answer.This link should be very helpful.
Did you check all the fuses? Other things would be a wiring harness connector becoming unseated or dirty, all the bulbs are burnt out or a wire is cut.
There are transistor testers. The down side is that the transistor has to be removed from the circuit to be tested.
If the current (amps) supplied to the appliance(s) plugged into an outlet exceed the rated current-carrying capacity of that outlet, you can have problems. Examples are bad contacts from the sockets in the outlet to the prongs of the plug, causing excessive heat, and the circuit wires which...
Relay contacts The contacts could be in a normally open or they could be in a normally closed position depending on the type of relay it is. Most relays have their contacts in a C form configuration. This means that there is a common terminal to which the hot wire is connected and two sets of...
Hook the negative on one battery to the positive of the second battery. Connect to the positive on the first battery and the negative of the second battery. This gives 24 volts.
the bms system is working through the logic created and controlled by the controller and the sensors based on the return air sensor in hvac bms system
If the element has failed you will still have 240V going to the element itself: it just won't be causing the element to heat up. Make sure the dryer is unplugged! Then take the back off the dryer and pull the element out - it's usually held by just a few screws. BEFORE YOU UN-CLIP THE WIRES...
I = P/V is the equation. It depends what voltage the circuit has eg. I = 24000/110 or I = 24000/240 etc.
Ohm's Law states that the current (I) flowing in a circuit is directly proportional to the applied voltage (E) and inversely proportional to the circuit's resistance (R). I = E/R Another way of stating Ohm's Law is that the applied voltage (E) is directly proportional to both the current (I)...
A 250 MCM copper conductor with a insulation factor of 75 or 90 degrees C is rated at 255 and 265 amps respectively. This conductor can only be load to 80% capacity which allows a working current of 204 and 212 amps respectively. To obtain the full capacity of 250 amps a 350 MCM conductor will be...
I=2.083 AMPS.. I=2.083 AMPS.
Fuses and breakers are the main forms of protection on generators transformers and most other electrical equipment.
Interconnecting Two 9 Volt Batteries What happens "when hooking 2 9 volt batteries together" depends on HOW they are connected together. IF you connect the Negative terminals together, AND the Positive terminals together, then nothing happens other than creating a 9 volt battery capable of...
Xenyx 1204FX is not powered mixer. If your speakers are passive (don't have their own powersupply system), this means that you need to get an amplifier for them.
Type your answer here... it is used to find the insulation break down of the conductors from turns to turns and layers to layers.it is aninsulation test for the transformers
turn it on for about one hour and it will flash 5 times and then come on ACTUALLY... The above is just nonsense. Beep codes are still used to indicate basic PC problems. During the POST, (Power On Self Test) the computer runs basic diagnostics on most system devices. If there are any...
All modern automotive alternators have an internal voltage regulator. If the regulator is faulty, it can cause an "over voltage" condition. It is possible to open the alternator and replace the regulator; however, if the alternator already has a fair amount of mileage on it, I'd recommend that you...
...worn to the point that bare copper wire is exposed, not frayed, not otherwise damaged. You could also check the temperature of the cord to make sure it isn't hot to the touch and make sure the plugs, sockets and connectors are not loose and the the connection points are undamaged. Often people...
MOST LIKELY... when a dashboard back light is out it's usually caused by one or more burned out bulbs.
The most basic calculation is volts multiplied by amps of a circuit for a single phase load.

Answer . i am 6 grade and long ago i dropped my phone in a cup of water. it did not work for a long time so i put it away for like months. well i wanted to use it again so i got it and put it in the frezzer for like 4 or 5 minutes chargerd it and now it works even better. put it in the frezzer if...
Amperes (abbreviated as Amps, symbol = A)
A voltage is connected across a heating coil and a current flowing in the heating coil creates heat (just like in an incandescent light bulb). A blower motor helps disperse the heat from heating element to the area to be heated, like the hair. The hot air combined with the blowing help evaporate and...
Depends on how you connect them together. Connected them in a series and you will have 18 volts. Connected them in parallel and you will still have 9 volts just double the capacity of 1 battery. Click the link to see these 2 connections.
You would be substituting an approximate 400-Amp conductor for the blown fuse. A copper penny has about 1,000 amps per square inch and is about 0.75 inches in diameter. The actual amount of current burning the penny would depend upon how much of its surface is in contact with the fuse panel. I have...
yes there is but its under the passenger floorboard by the center console
The centre of the (secondary of the) centre tapped transformer is zero volts because that is the point in the circuit on which you based your measurement. If you were to connect the reference meter lead to the end of the winding, then the centre tap would have voltage on it. Its all a matter of...
It probably has something to do with the viscosity of the oil that is in the crank case. The heavier the oil the harder it is for the engine to turn over when the temperature goes down. In some of the most northern climates at the end of the work day the oil is drained and brought inside and kept...
A source of 208 volts can be obtained from any two legs of a three phase four wire 208 volt system. The two legs are classed as single phase 208 volts. The lead tags can be L1-L2, L2-L3, or L3-L1 all of which will give you 208 volts. Any of these lead tags to the grounded star point (wye) will give...
Transformers can have multiple taps to increase or decrease voltage and each tap either adds or subtracts windings to the transformer.
by using a Digital Multi meter just check the voltage and it will also give you the sign with the voltage value
Megger is a brand of tester that measures the resistance to ground"earth" through a conductor that you can not visually check. The tester normally can put 500v-5000v on the conductor to check the ground resistance by measuring the induced current. R=I/V
Connect the positive terminal on one battery to the negative terminal on the other with heavy wire and battery clamps. Connect the remaining positive terminal to the metal chassis of the tractor, and run the remaining negative wire to the items to be powered, with any luck at all, through a fusebox.
All electrical relays consist of two circuits. 1.. A control circuit that utilizes a control voltage with a minimum current to switch a 2.. Power circuit requiring much greater current. The advantage of using this type of circuitry is that the switches or sensors that control large loads can be very...
The voltage drop should not exceed 3% on a feeder or branch circuit.
A short circuit is said to have occurred when the supply and return wire are directly connected without first passing the electrical current through a device which uses the current. For example, if you have two wires that are supposed to operate a light bulb, but instead you connect them together,...
Yes, just make sure they are connected in Parallel. (+ to +; - to-) In series they wil be 24 volts and will fry most anything thattakes 12 volts.
Its not. Its that the power company has to be able to have an easement to be able to conform to certain regulations. Like cutting the trees to make sure there are no power outages.
When an electrical appliance becomes faulty or ground fault exists, and excessive amount of electric current flows and can produce a large amount of heat. If the excessive electric current is over a certain value the miniature circuit breaker will "TRIP" automatically to break the flow of current...
