[C320-list] Autohelm depth display flashing zero...sometimes

[Onat Dogruer]

Flashing display is loss of data signal from transducer.  NMEA wire
connections may have dirt or water (corrupting the data signal). Can also
wrap a bit of electric tape at the junctions to prevent water/dirt getting
in if the pod is not keeping watertight seal.

Best,
Onat
