motor hook-up
what i think you have is a single phase dual rated motor with 3 windings that can be connected in series for high (460V) or paralell for low (230V) , if you read the leads and find three identical (or as close to identical) ohm readings you will take one from each set and connect to L1 and the remaining 3 to L2 for low volts, for high volts you connect L1 & L2 to one side of two of the windings and the remaining connection is just a splice connected to nothing, you would be putting the windings in series. send the picture so i can see it anyway to be sure....... hope this helps, jim
