hey i just figured out a cool way to check for ohm meter damaging the magnetics while checking continuity of coils-you hook up an inductance meter, like a BK 875B, get a reading on the pri, leave the meter on, ohm out the secondary using a variety of meters you want to check, the dc from the ohm meter may or may not cause a drop in the inductance, which you are watching as you connect the ohmmeter.
