I hope someone can help me.(adsbygoogle = window.adsbygoogle || []).push({});

I have an old 30 HP motor that I need to get working...if possible.

It is a 12 wire Toshiba, dual voltage. 230V 460V.

To wire for the low voltage the nameplate says:

connect wires 4,8,10 and 2 to supply 1.

Wires 9,5,11 and 3 to supply 2 and

Wires 6,7,12 and 1 to supply 3.

Someone has cut the wires and removed some of the numbers. The only identifyible numbers are 4,9,6,8,5 and 7.

Wires 1,2,3,10,11 and 12 have no numbers.

I have an electronic multimeter with resistance measurements.

Is there any way I can check resistances between what I know and what I need to know to identify the remaining wire numbers?

FYI: for high voltage hook-up the wires are paired:

6 and 9.

4 and 7.

8 and 5.

10,2 and L1.

11,3 and L2 and

12,1 and L3.

I appreciate any help.

Ian.
