Jenn-Air Cooking Element Doesn't Heat

Oven Repair (including Ranges and Cooktops)

Hello,
I have an old A122 Jenn-Air cooktop, and the large heating element on the Black burners (there are also white plastic-top burners that are working) isn’t working. I replaced the element to no avail.

I also swapped the wiring, so that the wires that were going to the small element now go to the large element. Still, the small element works (off the switch of the large element), and the large one doesn’t. This has me totally baffled.

Can anybody help?

The original element had a probe that extends the entire diameter of the burner, however the probe of the replacement element only extends half the diameter. This probably isn’t the problem, but I thought I’d mention it.

Is there anything I can check with a voltmeter? If I remove the black unit, voltages at the two outlets are 220V and 110V respectively. This is in contrast to the white unit, where voltages are 220V and 0V respectively. Maybe this is the problem? But I’m not sure what to make of it???
