[C320-list] Raymarine seatalk troubleshooting

[John Van Vessem]

Lachance,
   
  The very first thing I would check is inside the Navpod.  If you haven't already.  I believe you will find at least one fuse in there.

  I'm thinking its odd that 3 always reliable instruments failed between sails with no heavy weather in the mix. So it must be something common to all three like power or the seatalk bus.

Well...I'm with you in spirit. 

My wind instrument is dead and the autopilot reads
"seatalk failure".

Depth and speed work.

VHF is dead and it did have power at the set.

My first suspect was lightning, but...

VHF antenna apears intact as well as the wind vane.

Anchor light works.

Still could be lightning, but these rule out a direct
strike.

My next test will be to open the navpod and look for a
loose wire.

Barring that there are impedence tests for the vane on
the Raymarine website.
