the light is always on or always off, the feed rate switch is probably miswired. An erratic
light indicates a worn or defective feed rate switch.

alternator not regulating voltage properly or a bad connection. The OV light will come on
and deactivate the power feed control output until the problem is corrected.
OL
- This light indicates an extreme overload condition of the power feed motor caused
by a mechanical bind or a short in the wiring between the motor and circuit board. The OL
light will come on and deactivate the power feed control output until the problem is cor-
rected.
