Each coil lead is marked according to the following diagram.

Numbering is clockwise from the top and from the outside in. Terminal TO is the neutral lead on all high voltage connections. On low voltage connections TO is connected with T4, T5, and T6 to form the neutral terminal. The standard generator diagram and the terminal connections are on the nameplate of each generator.
