  • explain how 70volt transformers read shorted to ground on ouput side of anp

    It is a transformer, and transformers are nothing more than coils of wire wrapped around some iron. You are measuring the resistance of that wire, which will be pretty low. meanwhile transformers induce curent into the secondary from current through the primary winding. It works on turns ratios, not resistance.
    Education is what you're left with after you have forgotten what you have learned.
