[DG] [DG11] ST60 Total failure

Hi cdt

Thank you for your enquiry

first check power supplies and connections, there should be a good 12v measured between the red wire and the screen (shield) in the main SeaTalk wire, if there is a drop in voltage or loose connection then this will need to be rectified first.

try to connect the red to a separate +12v power supply and the screen (shield) to a -ve 0volt supply, isolate each instrument from SeaTalk and just try to power each one up on its own, this will identify any cable, connection problems or faults in a display which is causing the malfunction.

Thanks
Derek
