Hi Aaron,
For clearification purposes ...... on the RA Heater Circuit (revised: August 12, 2009)

Channel 1, probe to other side of 0.25 ohm shunt on the 555 circuit.
Is the probe between the .25 ohm resistor and the Battery (-) or between .25 resistor and the IRFPG50 Mosfet?

Channel 2, probe to mosfet side of 1 ohm shunt for load measurements.
Is there a 1 ohm resistor in the circuit diagram or is this a additional resistor required "just" for measurement and testing, and how is it connected to the circuit?

Channel 3, probe to positive of battery.
I assume this is the 24 volt battery bank and not the 12 volt seperate battery for the 555 circuit.

I think these answers may help me and other experimenters not totally familiar with what scope connections that were used for the common end results needed or to be found.

Thanks again for your efforts, help and support on this project, I'm afraid with the first harsh negative responses from the few we saw this would have had a much different result.

Best
