AC RECEPTACLES
Using a "Dr. Robin"or a circuit tester, check continuity between the two terminals at the rear of the
AC
receptacles while the receptacle
is
mounted on the control panel. When continuity
is
found between the
output terminals of the rece.ptacle with a wire connected across these terminals, the
AC
receptacle is
normal. When the wire
is
removed and no continuity
is
found between these terminals, the receptacles
are also normal.
