I don't have a diagram but aren't the three wires in supposed to be +, -, and ignition pulse?
Are they belling out to each other going back into the main harness or going back into the controller?
If its back into the harness I would think the + and - should most assuredly not bell out to each other, not sure about the ignition pulse wire.
If back into the controller the + and - might read between each other as its possible that it could be reading through the power supply or electronics maybe, but that value if actually read with an ohm meter should be greater than the 0.1-0.3 ohms we would read on a "closed" or "made" circuit.
