fuel injection problem on 1975 v12 jaguar

What I am wanting to do is test the hall sensor at it 4 wire connector to verify I have a good hall sensor. I am not sure how to do this? If I can verify it is good I can then work my way back but I need to know I have a good hall sensor first.

I have tested the hall effect sensor from the 4 wire connector. It is testing bad and giving a wave form very similar to the video I sent you. It jumps up to 7 volts when the magnet is over the board but then doesn't drop off as the rotor is turned pas the board. On occasion it will drop down but to .180 volts.

Hi Unknown,

not knowing how you tested, it should be 0V when magnet induces Hall sensor while ECU is connected and under power.
