how to check for grounded comp. windings



The use of an OHM meter is necessary for this task and a megger is even better.

Check S to R, R to C and C to S and all to ground.
The highest resistance will be R to S
The lowest will be C to R
The sum of the resistance from C to S and C to R equals resistance from R to S.
A megger will give you a more acurate result than an ohn meter.

Here is a manual that might help you understand some principles behind electrical testing of compressors. There is more to them besides being grounded.
