    My father has a JCB 530 with 4 wheel steering that isn't working. Checking the proximity sensors and was wondering on the sensor plug there is a black, red, & Blue wire. What is hot and which is ground? Is it supposed to have 12 volts to the sensor and then a ground? That is what I figured but not getting any power so wondering if we have another problem.

    No power at both sensors? Check fuse? Is the steering mode light on on the dash?
    If i remember right, there is a small led light on the backside of the sensor.
    Sensor wiring is usually a positive, negative, and output wires. Output can be either negative or positive depending on sensor type.

    After doing more digging found that somebody had run a jumper wire with a separate fuse to the front sensor and that wire had got broke where it went over the driveshaft. After getting that all back together it all works now. It appeared like somehow they had run the back sensor thru the same fuse because it had power after that to.

    Thanks for your info
