If you are talking about ignition systems and coils, the simplest way is to hold the coil wire or plug wire about 1/4 inch away from the car or engine ground (metal). Have someone crank the engine to check for spark. Do not be afraid of the high voltage in case you get poked. It will not kill you as it is momentary and you will let go of it if it gets you. I have been ZAPPED many times in my 40+ years as a mechanic.
There is also a test device consisting of a spark plug with an alligator clip that you can get at an automotive parts store. It is a spark plug that has the gap set at about 100 thousandths. You can attach the spark plug or coil wire to it and the alligator clip attaches to the block or ground. You can then observe if the spark will jump the gap while someone cranks the engine.
They are about 10-15 dollars....

Why do signs read Danger-High Voltage rather than Danger-High current?
Electricity is transferred with high voltage and low current to reduce transmission loss ( I2R , where R= resistance of wire). As high voltage is present in transmission lines, Danger-high voltage is written.
Who measure of charge differential voltage?
Any one using a voltage test instrument can measure charge differential voltage.
What is the minimum value of high voltage?
Well, the word "high" can have different meanings in various work-areas. To an electronics specialist, "high" voltage can be anything above 5-10 V. To a home-electricity-technician, "high" voltage is anything above 50 V. To an electricity-company-technician, "high" voltage is anything above 230 V. It is better to ask for a clarification each time you here the term "high voltage".
Is 0.01 Milli ampere is dangerous?
How high is the voltage that is being used? With high enough voltage any current is dangerous.
What is a battery discharge tester?
It is a meter with a high wattage resistor connected parallel with the meter that drains power from the battery while it is measuring the voltage it is used to test the condition of the battery if the condition is good there will not be a large voltage drop while testing the battery
How do you test the 11KV HT cables?
The test equipment used to test high voltage cables is a hi-pot test where a high DC voltage is a applied to the cable. This voltage can be from 150% to 200% of the working voltage of the cable.See related links below.
Can a high voltage transformer be megged with a megger meter?
No. A megger's output voltage is not high enough to test the insulation of a high-voltage transformer if, by 'high-voltage transformer ', you mean a distribution transformer or power transformer. Instead, a high-voltage test set or 'pressure tester' (e.g. a 'HiPot' tester) must be used, as these produce far higher voltages.
Where is a good laboratory to test out High voltage experiments?
A good laboratory to test out high voltage experiment should be a government owned laboratory, or one that is government approved.
Why is a high dc voltage applied to a transformer for testing?
A high dc voltage would be applied to test the insulation between the windings.
What is a high pot voltage test?
'High-pot' is short for 'high potential', and it is also the trade name of a high-voltage test set used for testing the integrity of the insulation of high-voltage cables and other equipment prior to putting them into service, or following maintenance.
Why were instrument of a transformer placed on a high voltage side in short circuit test?
I assume "tension" in this question should be replaced with "voltage". Short circuit tests are often performed from the lower voltage side of the transformer, since a lower voltage source is then required to perform the test. Often times the test lab may not have a source that can output a high enough voltage to perform from the high voltage winding.
Why high voltage is kept open in open circuit and low voltage is shorted in short circuit test?
In Short circuit test High Voltage side is feeded with 2-5% of the High Voltage rating to circulate approximately full load current in low voltage winding by short circuiting it. Low voltage is generally short circuited to facilitate measurements because it is more difficult to measure the quantities at high voltages.
Where is the high side of transformer on open circuit test?
high voltage side call primary
Why open circuit test is performed on low voltage side?
generally open circuit test is performed on the low voltage side.....not on high voltage side.... becuase on low voltage side, we can apply that low voltage very easily ( i.e with a less amount of source is required)... whereas on high voltage side, we need a large power source in order to apply full voltage... in short circuit test, we will test on high voltage side by keeping Low voltage side being short circuit.because high voltage side needs less current source than low voltage side....
What are the applications of high voltage?
some of the applications which i think are:high voltage power transmissioninsulation testingmeasurement of insulation resistancebreakdown voltage measurementsmeasurement of electric stress on different materialstesting of power transmission equipmentslightning simulationstudy of high voltages transients/surges on transmission lines
What is A BNC test Cord?
bnc test cord is used to transfer voltage or charges from high potential to low potential
Why High voltage test for cables?
High voltage testing is performed to confirm the integrity of a cable's insulation. It is always carried out after a new cable has been installed and terminated, or whenever a new joint is installed.
