Two Times Can't be a Coincidence...Dart not Firing

OP
Yes you can test the magnetic pick up. There are three tests. 1) if it runs, it's good. 2) you can ohm it out, and compare it to the spec, and 3) you can see it in action by checking the A/C output while spinning the driveshaft by hand.
As to #2, IDK the spec. but I can offer a guess, probably less than 300 ohms, and more than 200.Ima guessing.
As to #3, You will need an analog meter, with a millivolt scale.Every time a reluctor vane passes by the sensor, it will generate an A/C spike. Some digital meters need a peak-hold feature to capture it. Not my dynosaur.
