ABSTRACT:
A Nichrome wire resistor is connected in series with the motor of a motorized fishing reel. A stabilized voltage is supplied (selected by a potentiometer) and a transistor switching circuit is arranged to actuate a signal if the voltage drop across the Nichrome resistor increases above the selected reference voltage (due to the voltage drop effect of the increased current through the motor if it is overloaded).
