Default Re: Testing a transformer for shorted turns

I would be very careful using this method. If you hold the momentary switch on for more than a moment you could burn out the transformer winding. The max duration of the moment is dependent on the winding resistance, wire gauge and how stiff the battery voltage is , one second could be enough to burn out the winding . I would use a sig gen and voltmeter instead.
