There are a number of ways to test the output voltage of the transformer.
Oil furnace transformer test.
November 11 2013 an oil furnace works by having a high voltage ignitor create a spark next to an oil nozzle.
I did one earlier but it was not installed on the oil burner.
Some options may also use as little as 24 volts.

The most accurate is to use a voltmeter capable of measuring 10 000 volts.
Heating service technicians use a special high voltage tester to check the transformer.
Although your oil furnace burns fossil fuel it still needs electricity to light the flame.
The video below can help you if you need it.
This one shows how to test the transformer spark on the gun oil burner.

Transformers regulate the voltage in circuits but in some cases these can go bad and cause a circuit to not.
The nozzle compresses air and oil transporting it to the spark where it is ignited to create heat.
Transformers are an electrical component that transmit electrical energy between at least two circuits.
The transformer steps up your 120 volt house voltage to several thousand volts to produce a spark across the terminals of an igniter.
Finally test the newly installed transformer with a voltage tester.
Furnaces of all types such as electric gas and oil furnaces will use transformers with 120 or 240 volts.
