Although I have seen a fusible link in many types of electronics, what has my mind wandering this time is an automotive repair project.
The heater fan quit on 94 ford escort. I traced it to a speed control module. The fuse that fed the module was intact.
Mounted on the module are 3 resistors in the form of bare resistive wire, each one a different gauge, wound in the shape of a spring and a fusible link.
Everything is in series. 12v into the fusible link which feeds the fattest gauge resistor which feeds the next fattest gauge resistor which feeds the skinniest gauge resistor.
The connector side is wired to taps between the resistors to allow different voltages to the fan motor.
Thanks for your insights.
