What would you like to do?
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.

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.
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
If Your Battery Is being drained Dont Just Assume It is A Short .....:) It Could be The diode In your Atlenater That Has Went bad A Diode Is Like a Water valve it …Only Lets Current Flow One direction But if it goesa Bad that it Will Let The Current Drain From the battery .....:)
Have an electrical short draining battery I believe short is under dash Also it's an uncontrollable circuit I disconnected all fuses relays still draining battery. This is a 2000 Ford Ranger 4x4.?
Having the same problem. The answer is that I am going to have to take an electrical tester, charge the battery back up, then trace the live wires. There should be no live wi…res when the key is off.
If at battery,parallel circuit shorts then equivalent resistance of circuit becomes approximately 0 Ohms,and therefore as current follows low resistance path infinite amount o…f current due to low resistance will flow through the wire so,entire parallel circuit will short out,but wire will burn and battery may get damaged.

Yes it could over heat and explode. Don't do it.
To save keep blowing fuses or causing more damage, it is better to use a multimeter, set to resistance to check the power supply. Working with a circuit diagram, try to elimin…ate sections of the circuit by disconnecting them. Zero resistance across the power supply rails will show that there is still a short. Remove complete sections of the circuit be removing a convenient wire link, or at the extreme, you can cut through the printed circuit and repair afterwards. It all depends what kind of circuit you are working on, from delicate electronics to heavy electrical plant. Try to work methodically so that you don't retrace your steps, or be fooled into thinking something is clear of faults when it isn't. It definitely helps when you have a clear understanding of how the circuit should work and can read a diagram.
You would have infinite amperes if there was no resistance in the battery plates, the battery terminal posts and in the wires that are shorting the battery. But ther…e is always resistance in those things so - depending on the thickness and therefore the effective resistance of the wires that are shorting the battery - the short circuit current will be from a few amps to many hundreds of amps and, unless someone sees it and acts quickly to remove the cause of the short, that current will continue until the battery either explodes or just runs down very fast. I've seen them go both ways, along with the shorting wires smoking and then glowing like an electric fire, and also I have seen molten globs of hot metal dripping off from carelessly misplaced tools such as heavy screwdrivers, particularly if made of aluminum, and such things as small wrenches.
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.
Yes. But if the short circuit is directly across the battery, thenit doesn't harm it for very long, because the battery is destroyed almostinstantly.
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.
While I can't think of any reason why it would, it seems to. When I leave my iPod totally unplugged, it discharges very slowly, only perhaps 20% per day. If I leave it plugged… into my Xbox, it charges while the Xbox is on, but rapidly discharges while the Xbox is off, for some reason.
The current will increase to a very large value
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.
A short will not drain the battery it will blow a fuse. It may be the battery has a dead cell, or some light is on draining the battery. It can also be a stuck relay.
Insulated caps can be installed over the exposed terminals to prevent the battery from being shorted out.
A battery cannot be drained by a shorted diode when the ignition key is off.
