When a self-excited DC generator's field has lost its residual magnetism due to a prolonged idle period, it will fail to produce a voltage. Flashing the field is the procedure used to restore the residual magnetism. Using a 12 volt storage battery, how is this performed?

Question

Accepted Answer

The F1 and F2 leads are disconnected from the generator. The F1 lead is connected to the positive terminal of the battery, and the F2 lead is connected to the negative terminal.

Answer

The A1 and A2 leads are disconnected from the generator. The A1 lead is connected to the positive terminal of the battery, and the A2 lead is connected to the negative terminal.

Answer

The S1 and S2 leads are disconnected from the generator. The S1 lead is connected to the positive terminal of the battery, and the S2 lead is connected to the negative terminal.

Answer

The F1 and F2 leads are disconnected from the generator. The F1 lead is connected to the negative terminal of the battery, and the F2 lead is connected to the positive terminal.
