Testing oil burner transformers & cad cells
In reading the Beckett burner won't keen running it was said the transformer was tested. I would like to know how you test a 12 or 14,000 volt transformer. How does one measure that much voltage. Does the voltage have to be 14,000 volts or is 9,000 volts OK ? As for testing cad cells can it be tested with a meter? And if so how???
