Use of an Ohm Meter is the best, and only way I can think of, to test any kind of short circuits. Since you used the word track in the question I'm guessing this is a model train problem. The first thing to do is check the voltage at the transformer (electrical source). Then check the Ohms of each track. This will tell which track has the short. Moving one test lead up the track should locate the short. I the train doesn't move when the power is applied, the problem is probably a broker solder point.

∙ 9y agoTo check a short circuit with a Multimeter, the operator should not be standing in water. The Multimeter has two wires, one red and one black. The black wire is placed on a metal device to ground the terminal, and then the red wire is placed on the wire that may be the source of a short. In the case of many wires, each wire is tested separately. If the Multimeter does not move off of zero, then this indicates a short.

∙ 12y agoA short circuit should have less resistance than normal, as it is now in parallel, the amperage has more paths to flow through, so put an Ohmeter on the circuit and see. Not really sure as I am only in 3rd year and have just finished Electricity course.

How do you test a thyristor module using multimeter?
You can check if it is shorted, but without coordinating the gate and anode voltages with the cathode, you cannot test a thyrister (SCR) with a multimeter. Check it out of circuit for shorts, then check the circuit, then test it in operation. Anything more advanced will require an oscilloscope.
How do you find shorts and opens in an electrical circuit in multimeter?
An open circuit essentially has an infinite resistance. It is shown on digital multimeter as OL. (Open Line) A short circuit should read zero, or nearly zero, depending on the accuracy of the meter.
What color is hotwire in a typical 12 volt circuit?
Normally it is Red but not 100% of the time. Always check with a multimeter.
How do you know when you have a circuit?
tuned circuit
Why is it harder to measure amperage than voltage whit a digital multimeter?
Because to measure amperage you must connect the multimeter in series , in order to do so the circuit must be broken first. In the case with voltage measurements the multimeter probes must be connected in parallel which is far easier because connecting the multimeter this way the circuit will remain intact.

What purpose might the multimeter serve in maintaining and troobleshooting a computer network?
With the multimeter you can measure the voltage on parts of the circuit board. You can also measure the resistance of resistors and make sure there are no short circuits in the circuit.
What is infinity on a multimeter?
If is being used as an ohmmeter it usually means an open circuit. A switch may be open, or a wire is broken (not a short circuit)

Can I check the capacitor value by using analog or multimeter?
You can see if the capacitor charges and discharges with an ohmmeter. You can check the value of the capacitor if the multimeter has the facility. With an ESR meter you can establish the value of the capacitor while in circuit.
How do you measure with Multimeter a motor or integrated circuit IC for failure?
The voltmeter function if the circuit is energized or the ohmeter function if looking for short or open circuits
How do you check amp draw?
Amperage is measured by a multimeter. First determine the amperage rating on the multimeter. Next, select the appropriate setting on the tool. The next step is to set the range on the multimeter. Make sure to plug the leads into the appropriate terminals. Run the circuit through the multimeter to measure the current. Turn off the breaker, make sure the AC circuit is turned off, then rewire the circuit.
How you use a multimeter?
A multimeter is an instrument used to check for AC or DC voltages, resistance and continuity of electrical components, and small amounts of current in circuits. This instrument will let you check to see if there is voltage present on a circuit.
