These usually connect to the auxiliary winding of the generator. If your generator doesn’t have an auxiliary winding, these are sometimes jumped from the sensing lines (depending on the specific model variation). 3. Exciter Output (Field Control)

Ensure the engine is off and the battery is disconnected. High voltage in the terminal box can be fatal.

When you open the PDF file (which is usually 1-2 pages, vector-based), you will see a schematic showing:

Use a multimeter to identify the six or twelve wires coming from the main stator. Mark them: U1, U2, V1, V2, W1, W2, and auxiliary D1, D2. Do not rely on color alone.

and White wire (- Negative) typically end in spade terminals. These attach to the generator's exciter field (F+ and F- or slip rings) to control the rotor field current. Adjustment Procedures
