Can I use a car alternator's stator as an isolation transformer for 110AC?

No - the separate windings don't intertwine in the way an isolation transformer requires and I would bet the insulation breaks down well short of the 160 volt (roughly) peak of 120 RMS AC voltage.Can I use a car alternator's stator as an isolation transformer for 110AC?
No the winding of the alternator differ's from the transformer it's not the same
