Hi all,

My depth/speed and wind instruments have stopped working. To be honest, they have been intermittent for a while, sometime they would come on, other times not.

Is this corrosion at a connection somewhere?

Any ideas of what to check first? They're mounted on the hatch garage and would like not to have to take that off.

Cheers

They probably get their 12V supply over the Seatalk cables. Check the main power connection into the back of your chartplotter and then the Seatalk plug connections from there to the instruments.

If the chartplotter also flickers then check the power connection to the chartplotter from their source, probably at the switch panel.

They may get their supply via Seatalk, or they may get it independently of the plotter even though all are joined together via Seatalk to share data. Do you have a switch for the plotter and a separate switch for those ancillary instruments or one switch for the lot? Could be something as simple as a fuse gone or a dodgy connection on the supply to those instruments, separately from the plotter.

One switch for the lot and the plotter appear to be working fine.

I think water has gone under the hatch garage and corroded the connections to the depth and wind screens

I'm not sure how you could wire up the power to the instruments without using the Seatalk port? Is there another power port on the back of ST60 instruments?

I guess it's just done in parallel. I have a switch for "plotter", one for "autohelm" and one for "nav com" which is all the rest, though they're all connected through Sea Talk. Sea talk complains if I don't switch one of them one and stuff starts beeping with "seatalk error". I don't try to understand it even though I wired it all up about 13 years ago based on what was already there. I just turn them all on.

Nope, but if you don't bother with the Seatalk1 network then these .....

... are used to power the device and connected directly to +12v and ground, with the yellow data wire not used.
 
I'd start by checking the back of the instruments themselves... I had a similar issue when I first got my boat... Unfortunately in my case it was a rotten pin in one of the instruments... Once replaced... Everything worked as expected..

They will probably powered over a Seatalk 1 daisy-chain like the diagram I just added above. The Seatalk1 cables are reasonably robust so I'd check the power going to the hatch cover first if you can identify the power cable as a lot of the sensor cables will be fed in there too I would imagine.

You could have one faulty instrument which is taking the whole daisy-chain down or a faulty power supply. I think you will probably end up taking it all to bits anyway, so perhaps best to bite the bullet and get on with it. At least afterwards you would have peace of mind that everything is clean and well-connected and not be worrying when they are going to give-up again.
 
ok so chart plotter has its own switch on the panel and is working, but none of the instruments or autopilot are working

I am thinking it may be just the fuse.

Anyone know where the fuses are on a Jeanneau Sun Odyssey 32 from 2003. They are not obvious.
 
There is only one cable to the back of the chart plotter with a label 'power and data'.

I am struggling to access the back of the instruments themselves. I think that hatch garage may need to come off
 
Going through the manual, it would seem that the autopilot has its own 12A fuse and it is common to power the other instruments off that.

I am going try and find that fuse, as tri data, wind and autpilot have no power.

The plotter has a separate switch on the panel and is working fine.
