The most accurate is to use a voltmeter capable of measuring 10 000 volts.
Oil furnace transformer test.
The nozzle compresses air and oil transporting it to the spark where it is ignited to create heat.
The ignition transformer takes 120 volts ac and transforms it into 10 000 volts ac to ignite the oil droplets.
Furnaces of all types such as electric gas and oil furnaces will use transformers with 120 or 240 volts.
This one shows how to test the transformer spark on the gun oil burner.
Heating service technicians use a special high voltage tester to check the transformer.
I did one earlier but it was not installed on the oil burner.
Transformers are an electrical component that transmit electrical energy between at least two circuits.
November 11 2013 an oil furnace works by having a high voltage ignitor create a spark next to an oil nozzle.
How to test a transformer.
There are a number of ways to test the output voltage of the transformer.
Transformers regulate the voltage in circuits but in some cases these can go bad and cause a circuit to not.
The video below can help you if you need it.

Although your oil furnace burns fossil fuel it still needs electricity to light the flame.
Some options may also use as little as 24 volts.
