Abstract A drum rotation indicator for a power driven cable drum operated by a control lever, which includes an arbor rotatably mounted within the control lever and having an exposed end with a thimble-like recess. An electric motor rotates the arbor, and the motor is driven by a signal generator driven by the cable drum. A control circuit triggers operation of the motor in one direction or the other upon rotation of the generator in one direction or the other, and a tachometer driven by the motor limits the effect of the generator so that motor speed is held proportional to generator speed.
