When most people say "short," they are talking about a parasitic load, a circuit that is always on and drains the battery. Take the negative cable of the battery post, take your test light (ice pick type) and connect betw battery post and negative connector. Make sure everything in the car is off (dome light, amplifier, for example). If you have a current drain at this point the light will be on. Pull fuses one at a time and watch to see which one turns out the light. That will be the circuit your parasitic load is on. Get a wiring diagram and check the wires/switches/components on that circuit. For a real short, which blows fuses as fast as you can change them, you need a special circuit breaker that fits in the fuse panel in place of the fuse. This will power the circuit enough to work with it, but prevent meltdown. Now that you have current flow, you can run a small compass over where the wires for that circuit are running and watch for the needle to switch directions. Ask at the parts store, I don't recall what they call this ciruit breaker.

How can a tone generator be used to locate a short circuit?
Yes you can use both. They are also acutally the easiest way to find a short in an automotive circuit.
What is the function of fuse in automotive application?
Same as any fuse in an electrical system- to protect components in the electrical system from damage in an overload or short circuit.
What can you use to find a short-circuit?
A short circuit would blow a fuse. Most fuses are marked as to which circuit they protect. Now that you know which circuit is shorted you can examine the suspected circuit for problems like damaged/pinched wiring to ground.
What you find from short circuit of power transformer?
A: Usually smoke and smell
How do you reset a automotive circuit breaker?
Most automotive circuit breakers reset themselves after they cool off. Some bigger trucks use circuit breakers that are reset manually. They have a button you push in to reset the breaker after it has cooled off.
When you will get to know that short circuit will happen?
1. That if a short circuit occurs we will get a sign before short circuit will happen or not ? 2. what we can do ? 3. how fuse can get a short circuit ? 4. which wires we have to use from preventing short circuit ?
BMW 325e electric window circuit breaker reset?
Resetting Automotive Circuit BreakersWithout doing a "hands on" troubleshooting of your vehicle no one on this site can tell you specifically, what is causing the problem, or where to find it. It has been my experience that all of the circuit breakers for automotive applications are self resetting.Inside, they use bimetallic strips, and reset themselves when the circuit current overload, or short circuitconditions, has been removed/eliminated, and the bimetallic strip has cooled down.IF your breaker is not resetting itself after a reasonable "cool down" period, then that suggests:A short circuit condition somewhere in that circuit, orAn overload condition due to the addition of too much "extra" electrical equipment [like for example, a "monster" audio amplifier, or a light bar set], orReplacement of an electrical device with one which uses much more current than the replaced device, orA defective circuit breaker.
Why does the horn blow when you brake and turn?
The problem here sounds like a short-to-voltage between the horn circuit and the brake or other circuits. This essentially means that when one circuit is powered on, such as your brake light circuit when you depress the brake pedal, an additional circuit is also powered on by that circuit due to the copper wiring from the two circuits touching one another. If you are familiar with a DMM (digital multimeter) you can diagnose your wiring to find the source of the problem. Otherwise, you might be taking the vehicle to a shop to have it diagnosed/repaired. I would recommend an automotive technician that is ASE certified specifically in automotive electronics, not just any regular "mechanic."
What is the reason to use open circuit and short circuit methods to find Transformer losses?
The transformer can be tested on open and short circuit to find the iron losses and copper losses separately, which uses a fraction of the power than having to run the transformer on full-load.
Open circuit and short circuit test?
Open circuit means the circuit is not continuous . A short circuit is continuous but has a fault connecting between either live to neutral or earth .As result of this we saw that this answer is unsufficent to explain short and open circuit on the other hand you can use this answer also like i did:)
What do you do if the fuses keep blowing?
Find out why the fuse is blowing. You have a short or the circuit is overloaded.
Why does your 1991 park ave still have a drain even after you replaced your battery and alternator?
You may need to find a short circuit or a bad relay. Possibly there is moisture somewhere that is jumping a connection. Automotive electrical problems are difficult to track down yourself and expensive to have someone else do it.
