RE: ST-60 Speedlog issues
If the backlight level isn't translating it is usually a Seatalk bus issue. Troubleshooting is checking the connections on Seatalk bus from RP65 to Speed display.
I have enclosed the speed transducer test. I would be recommended to test, when you can remove the transducer from the water. Testing the Speed Sensor: Verify that the transducer’s paddle wheel is free of marine growth and rotates freely on its shaft Power down the instrument Disconnect the GREEN and SHIELD transducer leads from the instrument display or instrument pod. Connect a multimeter to the GREEN and SHIELD transducer leads and configure the multimeter to measure continuity or resistance. Slowly rotate the transducer paddle wheel by hand. Note that as the paddlewheel is rotated, the multimeter should alternate between an open circuit and a closed circuit with each quarter turn. As such one complete revolution of the paddle wheel should open and close the circuit four times. Should the multimeter respond as indicated above, then the speed sensor element of the transducer would be deemed functional. If not, then the transducer has failed and should be replaced. |
