Here is the basics, I have a heating coil that I think has a half-wave
rectifier in front of it (I am still waiting for the sales guy to call
back). I get about 20Volts AC when measuring the hot wire to ground,
0.8Volts AC when I measure the COLD wire to ground and 19.2Volts
between the hot and cold wires.

DC voltage osillates between 1.2 and 1.8 volts. So whatever it is it
inst straight AC.

I want to be able to calculate the wattage that the system is running
at, any help appreciated. The circuit havs 4.2 Ohemns of resistance.

I'd guess 100 watts.
