I did try this but got some really odd readings so I have done this
again using both my meters and still get some odd results.

0.2 ohms testing the two whites.
0.2 ohms testing the two greys
0.3 ohms between any white and grey.

0.2 ohms just shorting the meter probes together.

This means that the only real resistance is between any white and any
grey lead, of 0.1 ohm, which does not sound a lot to me.
