Bench testing 84-89 Carrera crank sensors.
 

Easy way to bench test 84-89 Carrera crank sensors.

You need a simple basic LED and a 330ohm resistor connected in series. You could also just use an LED but you run the risk of burning the LED out but just an LED will also work.

Works on any of these types of inductive sensors, like the ones in the 911, 944 and many BMW cars.
