Hi,

Does anyone have anywhere a copy of the wiring diagram for a Targa 47?
The reason for the request and background is our 12v system went down over Easter, first noticed by lack of VHF, then cameras, then stereo and then finally the extractor in the galley. This just about covers everything on the 12v system, so we could identify the issue. We've since contacted our local Fairline dealer, thinking this would be an easy fix, but seems not the case and also the factory seem to be less then helpful with any real information on older boats which surprised me.

Anyway if anyone has this info it would be much appreciated so the fault can be fully traced.
 
Evening P, that sounds a bit annoying. Did these various components fail one by one, or did they all fail together and you just noticed the failures sequentially?
 
If your boats engines are 24volt your 12 volt side may be supplied through a step down transformer which maybe the problem as you have lost all the 12v side
 
It will be a dropper that has gone. They convert 24v to 12v. Just had one replaced on ny new boat ( happened on sea trail so not down to me ).

Will most likely be in the general region of the switch panel.
 
I think all the systems went at the same time but difficult to say. First noticed the VHF on passage and then the cameras, all others were confirmed when we arrived in port.
The step down transformer is ok we tested this first, so it seems there's a break between that and the switch panel, hence the need for the wiring diagram. The 24 to 12v step down is located in front of you as you access the engine room via the aft door hatch from the platform (for those of you who know the 47). This is then fed forwards to the switch panel accessed from the mid cabin, the break is somewhere between the two?
 
Just to finish off this thread with some feedback reference for T47 owners in the future, it turns out there was indeed a second step down transformer that supplied the kit that all went down. This was located under the starboard side roof ling in the aft cabin (by the blind), there there are two step down transformers that need to be check one located as above and one located in front of you as you acces the engine room via the aft door hatch from the bathing platform.

Again Jimmy & jrudge's hunches proved to be correct - thanks chaps all now sorted!
 
Hi all, I am upgrading the OEM Raymarine E120 chartpltter to a Raymarine Element S on a 2008 Fairline Targa 47. Curious to know how/where the existing instruments are wired and best/proper way to do this. I surmise from my research on the internet that the all original raymarine stuff is Seatalk 1 and that I need to add a converter to Seatalkng to connect the more modern Element chart plotter and have it see the data from the transducer, GPS antena, and hopefully talk to the autopilot and provide location to the VHF etc. has anyone managed this? is it possible to get engine data and fuel tank % data from the EVC system in NEMA2000 format? Would be helpful if anyone that has done this upgrade could share how they did it and any lessons learned. For starters the new plotter is 12v instead of 24v/12v so I need to pull power for a different circuit from the DC panel or tap into an existing 12v circuit at the helm.
thanks.

Yes, you need a converter, get the Raymarine one. You will also need a STNG to NMEA2000 converter cable, to connect the plotter to the converter.

It will "communicate" with the auto pilot, but not control it.

The Element does not have a NMEA0183 port, so cannot send GPS data to a VHF that requires NMEA0183 data. Some ST60's have NMEA 0183 ports.

Interesting. I have garmin to Raymarine which will not control it but I would have assumed that Raymarine to Raymarine would work as intended.

Because it's an older auto pilot it will work exactly the same as your Garmin to Raymarine. For full control you need not only the same make, but similar ages too, same with Radar.
 
Thank you both. I have ordered the converter and STNG to NEMA200p adapter and a voltage regulator to get the voltage down to 12v on the original circuit and keep things “simple”. I plan to tap the converter into the ST1 network at the tridata display which is nearby and where the old e120 connected to that network.
As to the communicate vs control - what can I expect the new chartplotter to do for me by communicating with the autopilot? Can the chart plotter cause the autopilot to steer to a waypoint I select? Otherwise the only benefit would be having the depth, speed through water (typically not accurate) and water temp from the tridata and the GPS location from the GPS antena on the roof? The element has its own built in more modern gps receiver, which might me more accurate. Makes me think that the more useful info to pull into the plotter wold be the Volvo penta evc data instead or in addition to the ST1 stuff. This is on a Targa 47 without radar and a single helm installation, so not much else going on.
 
The autopilot will see the distance to go , heading etc and follow the track.

You wont be able to tell the autohelm to follow the waypoint from the plotter. So you set the waypoint. Goto. Then push the track button on the autopilot head.

I would use the Elements inbuilt GPS. Autopilot integration is as jrudge describes in post #14, so well worth having.
 
Agreed and thanks. Anyone have experience getting Volvo Penta D9s EVC data onto a NEMA2000 network? Found one company that sells a connector but curious what the real world experience has been with it.
 
Just bought the YDEG-04 and look forward to installing it. Excited to get that data on the element as it is very difficult to see/read the displays on the two tachs.
Will report back once it’s up and running.
Anyone know if the genaet is on the same network or as the Volvo Penta d9s or do I need a separate gateway to connect the generator to the NEMA2000 network?
 
Also did anyone ever locate the wiring diagrams for the Targa 47 circa 2008? That was the original subject of the post but did not see it.
