Saintly Fish Posted April 21, 2021 Share Posted April 21, 2021 I’m going to be fitting my new radar system soon. For the power supply, do I need to run a separate designated live for it, or can I piggy back off the power supply that feeds my two MFD’s?

suzook12 Posted April 21, 2021 Share Posted April 21, 2021 Can only answer that as seperate fused live feed, no-one else knows what the wiring is on your boat so to suggest a piggy back could well be overloading existing wiring. Even a solid state system can tip you over the edge in regards drawing too much current for the wire run length and and cross sectional area....... Piggy backing, if one of your mfd's develops a fault, you will lose your mfd's and radar. If all supplied and fused seperately, you will lose that mfd and nothing else.......

Odyssey Posted April 21, 2021 Share Posted April 21, 2021 Separate it out... easier debug when it doesn’t work (now or in future) 🙂 Saintly Fish 1 Quote Link to comment Share on other sites More sharing options...

Yes, it needs a dedicated fuse supply from the fuse box. piggy backing is extremely bad practise, especially from a single point of failure viewpoint.

Saintly Fish Posted June 11, 2021 Author Share Posted June 11, 2021 Another cable question. the location I want to site my radome is on the rear of my cabin roof. There is a cable void but is only about 20mm deep if that. The connector to the radome on the data cable has a 35mm screw fit. So this won’t feed through the route I have available. can the data cable be cut then re joined together? Quote Link to comment Share on other sites More sharing options...

I suspect it probably can (anything's possible right?), but it could be a potential point of failure or corrosion in future. Definitely no other way of routing the cable?

He says Garmin does a “field kit” for cutting and re joining. Apparently it’s a common problem. Quote Link to comment Share on other sites More sharing options...
suzook12 Posted June 11, 2021 Share Posted June 11, 2021 As has been said Neil, cut the indoor end and feed it backwards, keeps that end weathertight. Solder and heatshrink and shouldn't go far wrong, or research the plug type and fit new plug.... RS Components may be able to help as long as they're not dedicated plugs/sockets Quote Link to comment Share on other sites More sharing options...

Due to time constraints and being busy at work, I’ve now employed a bid to do the complete install for me!! Quote Link to comment Share on other sites More sharing options...

Especially if you’ve got to give up paying work to do it yourself... Solder and shrink wrap is prob easiest, make the join as close to the MFD as you can. Or leave someone else have to hide the cables and do the crawling in all places 😁😁😁 Quote Link to comment Share on other sites More sharing options...

Saintly Fish Posted June 16, 2021 Author Share Posted June 16, 2021 Got this install completed today. No carpentry needed. And yes, I do still have to remove the front anchor light. Think I’ll put a remote search light there instead, the power cable has been left in place. Any recommendations on those will be great fully received. Also a new deck work light to put under the rear of the roof. Geoff and GPSguru 2 Quote Link to comment Share on other sites More sharing options...

Saintly Fish Posted June 16, 2021 Author Share Posted June 16, 2021 9 minutes ago, JonC said: My recommendation for remote deck light is don’t bother, I have two that I don’t use because they just bounce the light back in your face. Surely a concentrated high beam search light doesn’t do that? I’d really only use it for docking in the dark. Or spying on the neighbours.

Odyssey Posted June 16, 2021 Share Posted June 16, 2021 Roof mounted lights are ok.... but not ideal.... I’ve got one on roof but I use my rail mounted more often...

Would it be ok here? Can the cable be run inside the S/S tube? Quote Link to comment Share on other sites More sharing options...

It can, but only if it was designed to do so, by that I mean pipe joints would have to be drilled before welding to allow cable through which is unlikely.....
