Every instrument technician who graduated from a technical school understands what’s going on; it can’t be.
Measure to see if there is essentially no resistance between A and B, with resistance present between AC or BC; connect it using the three-wire configuration.
I just measured it; the temperature gauge shows this: dizzy:
The manufacturer omitted a wire in order to reduce costs, and this has no impact on the measurements.
