so you will put the test wires on the ribbon connectors and use a metallic object to induce a signal?Testing a Hall Effect Sensor
There are a few ways to check a Hall Effect sensor that comes to mind. The first and most often gotten wrong test is to hold the sensor in your hand while it is hooked up to an ohm meter, then brush a metal object such as a wrench over the sensor. You should see some movement in the meter. Now this is not an absolute-for-sure test that indicates the sensor is in good condition. Although it does show whether or not the sensor can register a signal this is not a good/bad test result. You’ll need to test it further to be sure.

I have a wrench and a multi-meter. Unless anyone has a better suggestion I’m going to try this ^^^^
I wonder if you get a strong magnet, like the ones we find on car speakers, and put near the sensor it will register a input or a noise (or even will break the thing).
