To check your hall effect sensor on the RCEXL type ignition

If you are in a quiet area, - If you hear the ignition spark when you turn it on, and no spark any other time, the sensor is shorted.

In this test, you can also remove the plug from the engine and connect it properly in the spark plug boot with a ground wire from the threads of the spark plug to tio the engine. In this case you should see the plug spark once when you first turn the ignition on even without turning the engine over. The plug will not fire as a result of bringing the magnet by the sensor. Then your sensor is shorted.
