12 lead 3 phase motor / lead identification
(OP)
I have a 12 lead 40 hp motor. They marked 2 leads as T3. I know there is a way to identify the leads with a battery but can not remember the procedure. Can anyone help?

If most of your terminals are identified try first continuity with any multimeter.
