I'm assuming that those are the readings from the 3-pin connector, with the other end connected to the spindle. And that those are in the milli-Ohm range?

I'm asking because I've just been to measure my 2.2kW spindle...

All combinations between three pins were measured at 1.6 Ohm. (or, broadly speaking, 1600 milli Ohm) as...

A number of 1825, 1780 or 1755 would make sense, if on a milli-Ohm range (very unusual / expensive meter) - or possible presented as "1.825" Ohm?,

A value of 1825 Ohm would concern me somewhat.
