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.

How did you guess that, on the DC or AC
