Thank you very much.
I will proceed with doing that today.
I believe it is a Dual channel digital encoder. If i check it externally i would give 5 volts on supply connections and will check with 1 probe of multimeter to negative and second probe on other 4 pins. On each channel voltage should change to 0 or 5V by moving the **** slowly. Any channel does not show this, means encoder faulty.
The steer controller has sensed a fault in the tiller encoder.
- Verify 5 volts on pin #3 of the steering controller. If voltage is not present, check the steer controller for B+ voltage at the B+ terminal. Check the LED for solid light.
- If voltage is good on pin #3, check voltage at pin #1 to the steer encoder unit, pin #B to the pressure transducer, and pin #1 (wire 250A) to the steer motor.
- If any circuit is open, check the wiring harness for continuity. Inspect for loose or damaged pin connectors and for broken or damaged wires.
- If voltage is less than 5 volts at any point, check for a grounded circuit by disconnecting the following components one at a time:
* Steer Motor Connection
* Pressure Transducer Connection
* Steer Encoder Connection
Any voltage drop should be determined and the affected part replaced as necessary.
- Check the continuity of all wiring from the steering encoder connections to the steering controller, steering pressure transducer and the steer motor.
- Check voltage on wire #573, wire #574, wire #575, and wire #576.
* Voltage on each wire should switch back and forth between 5 volts and 0 volts as the steering encoder is slowly rotated.
* If voltage on all wires stays at 5 volts and 0 volts as the steering encoder is rotated, replace the Steering encoder.
