Test the Power Supply or Heat Demand.
Make sure exposed wires and bare terminals are not in
contact with other wires or grounded surfaces. Turn on
the power or provide a heat demand and measure the
voltage across the leads. The voltmeter should read
between plus and minus 4 volts of the supplied voltage.
