WebThis will result in a spark or "flash". That's where the term "flashing the field" comes from. One or two "flashes" is usually sufficient to restore the residual magnetism long enough to get the generator back to normal operation. As long as the residual magnetism exist, a generator can start working with a completely dead or nonexistent battery. WebNov 17, 2024 · Field Flashing of Portable Generators. The reason this works is because the electric motor in the drill will act as a small generator when spun backwards. The magnets in the drill’s motor induce a voltage into the motor windings, which is fed back through the trigger, cord and into the generators receptacle.
