Open electrical enclosure.*
Check the short-to-ground with an ohm meter.
Connect the ohm meter to each of the three terminal
screws and to the grounding lug. Test all three for resis-
tance. The minimum resistance to ground should be 1
megohm. If it resistance is less that 1 megohm there is a
leak in the system.
