Already did that. Getting 119.3VAC from the utility to the H.V. primary. I tested it off the big switching relay on the Smartboard. It went from a few millivolts right up to 119.3VAC right after engaging the start button.
I also measured amperage during operation. No surprise that it was only between 3.5A to 4.5A.
Next step(s)?
At this point I'm tempted to change out the magnetron (I have a replacement here) just to see if I was getting false 'good' readings when I tested it. But, that still doesn't explain the low current draw. . . does it?
