I hope someone can help me.
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.
