Starting up our 2009 R-29 for the first time this year. The Yanmar 6BY2-260 fired right up, but there is no data on the i5601e engine display and a steady alarm sounds. None of the fields in the diagnostics for the Yanmar display indicate the issue. The display is running version 3.0. The "Dashboard" for the engine on the Garmin 5215 is also blank as though never connected. I'm not sure if this is related or a separate issue, but the GPS indicates the boat is where it was hauled last fall (with a question mark), not the current location in our driveway. I've powered off the battery switches several times. Any thoughts or suggestions are appreciated.
 
I too have the Garmin 5215. I found the connectors to the back of the unit to be a problem. Undo each connectors retaining collar and move the plug in and out about ten times like your unplugging and plugging it back in. This will scratch the little pin connectors in their sockets and remove the oxidation. I then coated each pin with a Dialectic grease, plug back in and tighten the retaining collar. I think Garmin uses Lucas wiring, I had the same problem on my British car.

Good Luck, Leon
 
Thanks Leon. I'll give that a try. That may fix the GPS, but I'm thinking that with no data displaying on the Yanmar display that there is a common issue affecting both the Yanmar display and the Dashboard display on the Garmin.

We have a 2010 R29 with a similar problem. We bought the boat in November of 2016. During the sea trails everything worked. The 560i worked and the engine interface to the Garmin 5215 worked. Before we picked up the boat in the lower Chesapeake Bay the previous owner washed the decks and water from the compass got below into (at least) the Garmin Backbone. The check engine light was on, but the broker said it happened to him and it would go away. We were 1/2 hour out of the marina and into Chesapeake Bay when all the instrumentation went out, i.e., the Garmin chart plotter and the 560i. Contacted the yard that had worked on the engine and the 560i. Went there with the compass, paper charts etc. When trouble shooting the problem we discover the leak around the compass. It was bad enough that when we opened the Garmin backbone water poured out. Took most of the day to “fix”, which included separating the Yanmar backbone from the Garmin backbone. Took off the next morning we were about an hour and ½ half out when the 560i went to all dashes. Decide to go head. As we were turning into the Pautuxent River and the Solomons the 560i began to work again. We fueled up and headed to a marina for the night and the 560i had stopped working again. The next morning we were about three hours out when the 560i started to work again. Got to our marina fueled up and pumped the holding tank. When we stared up the engine again the 560i was out.

Next had an electrical systems tech look at it and he couldn’t fine anything wrong. Then had the local Yanmar dealer, said they found the problem the “T” where the 560i was plugged in was double terminated and the 560i was now working. That was the end of the season and the boat was hauled.

Next spring when the boat was launched the local Yanmar dealer did several maintenance projects. When we turned on the engine the 560i didn’t work. Played with it and found if we took the termination off of the “T” to the 560i it worked. i.e., it went from dashes to full engine data. Now my understanding is that “ain’t” right the backbone needs to be terminated at both the source (engine) and at the destination (the “T”) before the 560i. Anyway I tried to reconnect the two backbones using a Garmin power isolator and couldn’t get the two to talk to each other.

At a Tug rendezvous Pocket Yacht (the local Tug dealer) worked for 2 hours and couldn’t get the 2 backbones to work with each other.

Worked all last season with the Garmin and Yanmar backbones separated.

Going to try again this spring to find the problem. Have talked with Yanmar and that didn’t give me any answers. BTW the compass isn’t on the outside deck anymore.

So I am curious to see if you find a “cure” and will let you know if I find one.

Ouch, Jim! I hope I'm not in your situation. We bought our boat in November of 2016 and didn't have any Yanmar issues during the 2017 season other than some neutral safety switch non-starting, and low voltage alarms when using the thruster. Those were resolved during the season. The Garmin GPS worked great and displayed the engine gauges. I've read about leaks around the compass, but there are no signs of leaking on ours in the wiring cabinet behind the dash and above the hanging locker. On your tug is there more "backbone" wiring somewhere in addition to what's behind the dash? I've read about some boats having something behind the fridge, but I haven't pulled it out yet to look.

Chris,

Both backbones on our R29 are under the dash with access through the closet in the v-berth. We had several things fail last year; the inverted failed, the hot water heater failed and started to leak and the electronic module in the refrigerator failed. All got fixed and by the end of the summer every thing except for the interface between the Garmin and Yanmar backbones were working. Didn’t see any other connections for the backbones behind the refrigerator. One of my frustrations is can’t seem to find anyone who really knows the Yanmar backbone and all of the components. One of the problems is that Yanmar is no longer building our engines.

Overall we are very happy with the boat.

Jim
 
Thanks Jim,
I've removed, cleaned and reconnected all the connections on the back of the Garmin display as well as what I guess is referred to as the Garmin backbone below the electronics cabinet in the back of the hanging locker. I wish I knew how the data arrives at the displays. Should I be troubleshooting the data from the engine to the Yanmar display, or is the engine data delivered to the both the Garmin and Yanmar displays via the Garmin Backbone? Is there something I should be checking on the engine? I read a recent post where there were similar issues with a Volvo and there was a comment about possibly a small dead battery. There's nothing in the Yanmar Display Manual about a small battery.

Chris,

That data from the Yanmar comes from the engine; CPU to an interface and them via cable to a NEMA 2000 "T", off of the tee it goes to the 560i. The "T" is connected to the Garmin backbone either through a cable with the power wire cut ( old way) or via a Garmin power isolator "T". Need to do this because each backbone is individually powered and there can't be two power sources on a backbone. If things are working the Garmin recognizes the information from the Yanmar and all is well, For some reason on my boat the Garmin does see that it is connected to a Yanmar engine, but all of the data is corrupted and it causes the 560i to go to all dashes.

I saw the comment about a battery, but haven't run into that with anything I've seen about the Yanmar. That problem is I can't find anyone who really understands the Yanmar system, this includes Mack Boring in NJ or the local Yanmar experts. They all understand the engine, but not the interface. I have a couple of things I want to explore this season, but for now the two separate backbones are working.

An update on the lack of data on the display. I've learned that the display will show data when only the thruster battery switch is on. When either of the other two switches or any combination is on there is no data. So, with the thruster battery switch on, although I can't start the engine, I can now see engine hours, battery voltage, and the needles for the engine gauges appear. Also, there are two audible alarms and one stops after a few seconds. Displaying the diagnostics screen the check engine line and the two throttle diagnostic lines are highlighted. Thanks for all who have weighed in. I sure would appreciate some feedback from the factory!
 
If it was me, I would separate the Garmin equipment connected VIA Nmea 2000 from the Yanmar N2K tees. To be perfectly honest, I do not remember where they were mounted on your boat but believe they might be under the closet. Remove all of the tee's individually making sure there are no broken connections at the tee or node. The Yanmar wires were gray instead of the standard black ones Garmin provided. If this doesn't solve it, I would contact a Yanmar dealer to have them plug in their computer to read the codes you are receiving. I believe you are close to Winter Island Yacht Yard who is also a Ranger dealer which would be a good place to start. Last but not least, you might want to remove the Teleflex box and send it back to Yanmar to be updated if it isn't already.

Thank you,
 
If I was trouble shooting this I would have to start with where is the back bone getting its power? I'm not sure how your boat is wired but the engine battery should be the only battery to turn on the yanmar dash display and then communicate to the Garmin. The backbone should have its on power supply coming from a fused circuit linked preferably to the house battery so it doesn't see any quick voltage drops ( Engine battery or thruster battery should not power electronics or back bone). Once you find the back bone power source and confirm it is coming from the house battery confirm you have 12volt at the plug end that is providing voltage to the back bone. With house battery on and Garmin on your N2K should be linking all electronics with in your Nema system but each devise will not communicate unless it is powered up including the Yanmar. With the engine battery switch on and Yanmar ignition turned on communication should be liked to the Garmin and this is the only time you should read engine information on either the Yanmar dash unit or Garmin. The information you provided stating you can read the engine information when thruster battery is on but when you turn any other battery on leads me to think that battery connections may be incorrect or the battery banks are not being isolated properly. I would start with engine battery switch (on position) the only location voltage should be is engine components or possibly auto bilge pump( powered all the time) Turn switch off. Thruster battery (on position) thruster, generator, possibly windless voltage present, turn switch off. House (on position) all DC distribution components should be powered including electronics and N2K, engine and thruster components should show no power. After testing, if you saw any indication of voltages in different circuits you may have battery wiring issue or isolator issue. Remove the battery isolator from the system, make sure all battery connections are placed properly in the right location to the right battery. After you have confirmed all battery connections are right, all circuits are powered up right from the right battery switch, N2K is powered properly. I would then check the communication cable between the Yanmar and Garmin ( most likely ok if it did communicate with thruster battery on) then have the Yanmar technician read codes there may be multiple issues. If you disconnected your batteries for the winter and reconnected in the spring. Everything worked in the fall and now issues This is the first place I would look.
 
Question for Andrew. I’m confused. The Teleflex box? Is that the box between the ECU and the 560i? How is it updated and how would you know what the current version is and what is the latest version?

My problem is similar to Chris’s I can get data to the 560i but can’t get the two backbones to talk. Also, had to remove the terminator from the “T” that connects to the 560i. The two backbones as separated. Why they are separated is in an earlier post.

I haven't gone dark on these helpful troubleshooting ideas! Work gets in the way. And as the days tick away without a fix, so does our short season! Thank you, Andrew and Brian, for your 'most recent suggestions. I'm very ignorant and still learning about the networking, so please bear with me! Is the N2K connection device also knows as the backbone? Andrew, you mentioned disconnecting from the Yanmar N2K Tees. There is a connection apparatus (backbone?) in the hanging locker below the cabinet behind the dash electronics which I assume is what you are referring to, but this seems to be Garmin related, not Yanmar. I say that because several of the cables that I can trace run up to the cabinet behind the dash. I don't see any gray wires connected to this. Only black and one yellow. The other wires running to this connection I assume are coming from the engine and GPS antenna devices and are bundled in to spaghetti. I haven't yet been brave enough to separate all those wires to see if I can figure out where they come from. Remember, I'm also trying to troubleshoot lack of GPS signal and awaiting a marine electrician to test the antenna.

Brian, you are correct that there is something wrong with the wiring from the batteries. I haven't been able to completely straighten things out since buying. But it's now down to more of a labeling issue and meter feeds. The battery banks and switches don't jive with the battery meter displays on the Sunpower and dash displays. I think that's unrelated to this problem. I'd be the first to admit if I might have messed up connecting things for the season, but the batteries remained connected in the boat this past winter. So nothing has changed since everything worked last season. You suggest removing the battery isolator from the system. I don't know what a battery isolator is. Can you elaborate? I agree that the Garmin communication cable must be okay since it does work when the thruster battery switch is on.

Jim, I think the Teleflex box is the 560i labeled for Yanmar. But, as you can tell, I'm pretty clueless so double check! I think there's a post somewhere about what the current version was at the time of the post. I just recall that it was higher than version 3.x.

Thanks again to everyone for sharing your ideas!
Chris
 
If you have a owners manual there is a good basic wiring diagram in the manual page 30. If you don't have the manual there is a manual PDF in the Forum index- Ranger factory technical bulletins. Battery isolators are labeled as Charge relays. Like you said maybe not related but you may have a few things going on. Good luck.
 
Cris,

The Garmin “backbone” has a lot of devices connected to it. To Yanmar’s is just a single N2K T. It may be gray rather than black, that’s Yanmar’s version of N2K. To fined it, trace the cable from the 560i to the T. One side of the T will come from the engine the other will be a cable to the Garmin backbone. That cable should have the power lead cut. That’s because both the Yanmar and the Garmin are separately powered (This was the way it was done on my boat).

The following steps got my 560i working even if I can't get the two backbone to talk yet. Disconnect the lead going to the Garmin backbone. Put a terminator on the T. Then see if you’re getting any data on the 560i. If you’re still getting dashes try removing the terminator. That’s the way mine is currently working. It doesn’t seem right as N2k backbones should be terminated on both ends. If none of that works I'll let you know if I fined out anything else.

When I tried to reconnect both backbones Andrew pointed me to a Garmin “Power Isolator” T. (It’s just a T without a power lead). When connected the Garmin recognizes the engine as a Yanmar, but no data and the 560i goes to all dashes.

One of my frustrations is the 6BY2 is no longer made and I can’t fine anyone who seem to really know how that interface works. I have a few more things to try, but for now I’m just using the boat with the two not interconnected.

Jim
