I then disconnected the crank sensor and plugged the loom connector into a spare sensor that I have. I moved the sensor around the car. I found that the fault appears when the sensor is less than 12 inches from the car battery.
Does it happen when you put the sensor near the second (DTA) battery?

What make and type of battery is the vehicle battery?

As far as I know a battery should not do anything normally to cause the sensor to trigger. If you remove the vehicle battery from the car does it do it? Then put a load on the battery like a headlight bulb does it do it then? This will prove if it is the battery itself of the vehicle wiring very close to the battery.

That's a good idea.

Also, what's near the battery in the car?

Is there maybe a alternator nearby? Or maybe the powerfeed from the alternator to the battery.
Maybe a strange problem with the alternator which gives a problem with the cracksensor :S

I removed the alternator from the engine and it had no affect on the problem.
