How do you trace a short circuit that's draining the battery?
U disconnect the NEGATIVE battery cable & put a 12Volt test light IN BETWEEN the cable & battery post(connection) THen U start pulling fuses un- till the light goes off MAKE SURE U have ALL switches & doors shut because (doors-radio-etc) will turn on the test light.IF IT still doesn't go out after all the fuses have been pulled-THE problem is in a HARD WIRED CIRCUIT like the HEADLIGHTS etc.

Answer . Answer . Most of the time the battery is loosing charge on a mower it is bc the battery is going bad. The cells inside are wearing out and not holding a charge. …Replace the battery and usually the problem stops. If it is a acid fillable battery then make sure the battery has the proper amount od distilled water and acid in it. Also if it is a serviceable battery then I would replace it with a maintenance free battery anyway. A lot less to mess with. Good luck.
Yes it could over heat and explode. Don't do it.
What could be the cause of short circuit in glow plugs starting system of 106 1.5 diesel All relays have been changed check engine light on and battery continually drains diagnostic test inconclusive?
very possibly it is the glow plug relay, try dissconecting the relay for a day or two and see if the battery still goes flat, another test is to connect a multimeter or …12 volt test lamp to one of the glow plug terminals, if it stays lit all the time it is the relay if it goes out after about 30 seconds of turning the ignition on the relay would seem to be ok very possibly it is the glow plug relay, try dissconecting the relay for a day or two and see if the battery still goes flat, another test is to connect a multimeter or 12 volt test lamp to one of the glow plug terminals, if it stays lit all the time it is the relay if it goes out after about 30 seconds of turning the ignition on the relay would seem to be ok
Yes it does. A short circuited battery creates excessive heat from the rapid discharge. This heat damages the internal chemicals and component materials in the battery. In som…e cases can even cause explosions and fire.
How do you go about tracing an electrical problem that is draining the battery on a Hyundai Elantra?
My '00 Elantra had a similar problem. Above the brake there cable/wire was exposed/fried, etc.. and the front lights would never go off, therefore draining the battery. I ende…d up having to remove a fuse (panel above battery, there's a bunch of red fuses in there) everytime I stopped my car, to prevent the battery from dying until we figured out what it was. Bought the cable from the deal ($15), had it replaced and it works great now. \n. \nIf you are not comfortable or knowledgeable with the electrical system of a car, have it checked by a mechanic. If the above solution isn't your problem, you can isolate what's drawing the current using this method. You need a multimeter capable of reading AMPS. Remove the ground battery cable and place the multimeter between the battery cable and the battery. Make sure you DON'T run your car like this!! With the car OFF, see how much current is being drawn from the battery. Some current draw is normal, as your cars computer and radio memory functions need power to retain their settings. Start by removing a single fuse and replacing it, each time checking the current on the multimeter. By process of elimination, if you pull the fuse on the circuit that's causing the trouble, the current draw will drop. There's your troubled circuit. Then you'd need a wiring diagram, which you can find on hmaservice.com, and trace down the short circuit.
A battery stores CHEMICAL energy. Then, when a circuit is connected to it, the chemical energy is converted into ELECTRICAL energy (called "charge", measured in …coulombs) which is sent around the circuit as a flow of electric current (called "coulombs per second", which has been given the international unit name "ampere"). Batteries provide electrical energy. A battery sends electricity through the wires so that, for example, a bulb can light up or a buzzer can work. For more information see the answers to the Related Questions shown below. It's the power The battery maintains a difference of electrical potential between two points in the circuit. With the appropriate choice of components and interconnecting paths, the potential difference can cause a flow of electrical current through the circuit. The nature and arrangement of the circuit components determines the results of the current.
No they cn not
A somewhat imprecise term used to describe the condition of very low resistance across the terminals of a power source, resulting in very high current.
Do not ever do this. When a battery is intentionally short circuited, there is nothing in the in the electrical path to limit the current flow except the resistance of the co…nductor and the internal resistance of the battery. Both of these values are so small that their effects on the circuit are negligible. So if we assume the the resistance of the short circuit is 0 ohms (it will be almost 0 ohms in applied theory), then the current in the circuit will continue to rise until the conductor shorting the circuit or the battery itself is destroyed. This will happen extremely quickly and will potentially cause harm or death to any bystanders. Again, do not attempt to short circuit a battery or any other electrical circuit unless you are trained and qualified to do so.
When a wire is cut in a circuit, a gap is made and the current can no longer circulate, known as an open circuit . When 2 parts of a circuit touch, that shouldn't, for exam…ple - a wire comes loose and comes into contact with another part of the circuit, its shortening the route of the current in the circuit. So its a short circuit . When this happens 99.9% of the time the result will be a spike in amp's, so tripping any circuit protection, MCB's, fuses. A good example of a common short circuit is faulty windings on a 3-phase electric motor. If the resin separating the windings becomes damaged it can cause 2 or even 3 of the motors phases to come into contact causing the motors overload protection to trip.
Short circuit is the case when electricity, instead of travel through the design circuit path, jump across an unintended low resistance path and bypass the design circuit. A s…hort circuit is a path for an electric current to travel through where there is very little resistance. This path is often, but not always, through a wire connected directly to a ground, and is often, but not always, unintentional.
If the cables of the electric appliances is worn out or connected not properly,a short circuit may occured.The hort circuit has a very low resistance that almost all electric …current flow through it.Owing to the heating effect,much heat will be generated when there's excess electric current.If there's no electric device like circuit breaker and fuse,a fire will be occured.
In an open circuit, no current flows since there is no path to the load and ground. In a short circuit the supply voltage is directly connected to ground.
You have to remember ohms law Voltage = amp * resistance. Using some basic algebra you can rewrite the equation as amps = voltage / resistance. Since a short circuit has relat…ively 0 ohms of resistance, this increases both the amps and resistance which uses more battery capacity,power, and creates more heat.
A short circuit is a connection that is not expected, causing current flow where it is not expected. Often, a short circuit is a low impedance connection, causing the protecti…ve device (fuse or circuit breaker) to trip. The generic diagram of an electric device shows a power source of some type and a path for the current to flow from the hot side of the voltage source through a load and back to the ground for the supply. A "short circuit" basically shortens the path of the current before the load and back to the ground of the supply with a resistance that is near zero causing a high current to flow. I suppose you could say the path of the current is shortened and hence "short circuit".
The fact that it takes 3 days probably points to the alternator not charging, but a faulty voltage regulator can cause this also if you know for a fact that the battery is goo…d. Attach a voltage tester to the battery and monitor the volts as you disconnect the wire connector to the alternator, if it jumps up to 13 volts or so then the draw is there. Otherwise you can do the same test and disconnect various fuses to try and track down the item that is giving you trouble. A constant draw will probably make your battery read 12 volts or less when it should be up around 13 or 14.
1. Remove the negative battery terminal. 2. Put a 12 volt bulb in between the cable end and the terminal on the battery. 3. If you are having a drain then the bulb will light …up. 4. Watching the bulb pull the fuses one by one. 5. When the light bulb goes out after pulling a fuse this is the circuit that is being drained. 6. If after pulling a fuse the light gets dimmer but doesn't go completely out that means more than one circuit is draining the battery. Continue to pull fuses and put them back in to find the 2nd drain. When the light goes completely out you have found the second drain. For this diagnostic procedure make sure that everything is turned off on the car including the the dome light that comes on when the door is opened. Make sure the key is in lock and off. Make sure the trunk is shut.
