or at least determine if it is wye or delta...

Determine if the motor is WYE or DELTA - Electric motors, generators & controls engineering - Eng-Tips

Disassemble the motor and apply low voltage DC to a pair of leads. Check the magnetic field strength around the inside of the stator with something like a hacksaw blade. You may wish to vary the applied DC voltage until best results are obtained.
Delta: One winding group will be magnetized strongly and the other two groups will be at half strength.
Wye: Two winding groups will be strongly magnetized and one group will be either not magnetized or weakly magnetized.
