A ignition transformer tester

is the best thing as it tells you the output. Barring that, here are a few test. These work on the old laminate iron core trqnsformers and the new electronic ones as well.

From one spring to the other should be no more than 2000 ohms. They are also center tapped, so from each spring to ground should be 1/2 the read from spring to spring, and should be within 10% of each other. i.e. spring to spring 1500 ohms, one spring to ground 800, the other 700 = bad transformer as they are not within 10% of each other..it may still work , but it is on the way to failure.

As to whether it is interrupted ignition, that is controlled by the protector relay, the older 8184 series ran the ignitor the entire time, the 7184 series shuts it down after about 45 seconds.

great but don't

i was showing a guy how to test these once ouch! i had what i thought was a plastic 5 in. level nope alum. well the ignitor was good but be sure you put white wire to nuetural and blue to orange off relay older homes without proper grounds will kill these ignitors if not wired correctly. i do have a tester from sid harvey that works great. royboy
