If you look on the back of the ST5000+, the fluxgate port will be color coded, Gray, Red, Green, Yellow and Blue, you will remove the Blue and Gray wires and measure between them.

I removed the black and blue wire from the head unit. The ohms when checked on the black wire to blue wire is 7.8ohms.

When I perform an ohm test between the blue terminal and black terminal on the unit itself with the wires disconnected I get a reading of -4.59ohms
