With the isolation transformer you can connect the - lead right to the chaiss. Without the use of an isolation transformer you can measure the voltage from earth ground to chaiss ground. If you get 120vac flip the ac plug around and you should measure a small amount of ac, the difference from neutral to earth ground. Just make sure you don't have 120v from the chaiss to ground and you will be fine.

figure out what all those squiggly meant.
