What does Data failure J3XX mean on Simrad AP35 Autopilot System?
If your Simrad Autopilot System shows a Data Failure J3XX error, it indicates a wrong checksum on memory parameters or variables, causing the junction unit to use default values. Perform a 'Master reset' and then complete a new 'Dockside set-up'. Switch the system off and on again. If the alarm repeats, replace the Junction unit Main PCB.
What to do if compass data is missing on Simrad AP35 Autopilot System?
If your Simrad Autopilot System is showing that compass data is missing, it indicates that there is no data from the selected compass. If you have multiple compasses connected, go to the USER SETUP menu and select a different compass. Also, check the connections and the Interface menu settings. If the problem continues, consider replacing the compass PCB or interface PCB, remembering not to cut any cables as the PCB contains screw terminals.
Why is there a rudder response failure in my Simrad AP35 Autopilot System?
If your Simrad Autopilot System has a rudder response failure, and there is no response to rudder commands, begin by checking all connections. Next, check the Rudder Feedback transmitter link and inspect the drive unit motor and brushes. If the issue remains, consider replacing the junction unit Power PCB.
How to troubleshoot Comm. failure on Simrad AP35 active control?
If you are experiencing a communication failure with the active control unit on your Simrad Autopilot System, including the FU35 going silent, first press the STBY button on the 'Inactive' unit to attempt a reset. Then, inspect and repair the Robnet cable. If the problem persists, consider replacing the control unit or the FU50 PCB.
Why is the rudder test too slow on my Simrad AP35 Autopilot System?
If the rudder test is too slow on your Simrad Autopilot System, it may be due to excessive load on the steering gear, air in the hydraulic system, or insufficient drive unit capacity. Check for mechanical obstructions at the rudder, tiller, or quadrant and inspect the back drive force. Bleed the hydraulic system to remove any air. If the problem persists, replace the existing pump unit with a bigger one.
What causes J3XX current overload in Simrad AP35?
If you are getting a J3XX current overload error on your Simrad Autopilot System, it means the drive unit shut down due to excessive load or a short circuit. Check the drive unit, its installation, manual steering, and the rudder for any issues. Disconnect the drive unit; if the fault is still present, replace the junction unit Power PCB.
What does low 15 volt mean on Simrad AP35?
If your Simrad Autopilot System indicates a low 15 volt, it means the internal 15 Volt supply in the Junction Unit is below the limit. Replace the junction unit Main PCB. If the Mains voltage is 12V, replace the junction unit Power PCB.
Why is the Bypass/clutch disengaged on my Simrad AP35 Autopilot System?
If your Simrad Autopilot System indicates that the bypass or clutch is disengaged, it suggests a poor connection or open circuit in the bypass/clutch coil. Check the connections. Replace the bypass/clutch if it is open. Perform a new 'Rudder test'.
What to do if my Simrad AP35 Autopilot System keeps steering the boat off course?
If your boat is off course while using the Simrad Autopilot System, it could be due to extreme weather conditions, too slow speed, or the boat's heading being outside the fixed off-course limit of 20 degrees. Check the steering parameters, including Rudder, Autotrim, and Seastate filter settings. Increase the Rudder value. If possible, increase boat speed or steer manually.
What causes high supply voltage error on Simrad AP35 Autopilot System?
If your Simrad Autopilot System indicates a high supply voltage, where the mains exceed 44V for J300X or J300X-40 models or exceed 29V for J3000X models, first verify this using the System Data Menu. Then, switch off the autopilot and check or repair the battery charger.
