Help with motor wiring

[shockin]

I have an existing motor that is wired for "high voltage" (480v.) It needs to be re-wired for "low voltage" (208v). Easy enough to do. The problem is that it's not stated on the nameplate whether the motor is a Y or Delta.

My question is, can a person look for continuity between certain leads to determine if it is a y or delta motor? Or possibly with a megger?

The configuation on "high voltage" for a motor is the same for a y or delta so that doesn't give me any clues either.

Rolling the dice isn't an option

Thanks in advance for the help.

If 7-8-9 show continuity its y. light out is 789 1-4,2-5,3-6. if you have 3 pairs and 3 that light together its y. if you have 3 sets of 3 its delta. delta will light out 1-4-9,2-5-7,3-6-8.
