Yanmar Engine Display

[Chessie]

Ranger R27, 2013 Hull FML T2709G213
Engine: Yanmar 4BY2. Engine Display Yanmar 15601E
Chart Plotter: Garmin 1243xSV, software 28:10 Unit #3374574010
Autopilot GHP10
Problem: After about 2-3 hrs of motoring the engine display went blank, about 30 minutes later the CP indicated that it had lost contact with AP, although AP held heading. Pressed OK button on CP and everything reacted normally. The same loss of contact message appeared about every 10 minutes. Later the red engine warning light also came on periodically, Engine temp was steady at 190F and oil level fine. After anchoring overnight. We concluded it was best to head back to home port I left the CP turned off and used the auto pilot. About an hour from the harbor, I turned on the chart plotter and set a course to the harbour. Everything behaved normally. I’ve had a local mechanic inspect the engine and he determined that there was a low voltage (one volt) on the feed to display and this was the reason for the engine display being blank. He suggested , that the problem lay in the ECU or the connections to the display. Unfortunately, none of the marine services in our area have the Yanmar diagnostic equipment. Although the engine display is blank, the engine functions such as RPM, temperature, etc. are still displayed on the chart plotter. The only item not displayed is depth, although sea temperature is displayed. Any advice?

I get intermittent messages similar to yours when starting the boat with electronics on.You problems most likely is a low voltage problem. First thing I'd check is my ground (negative) connections as they seem to produce these type of symptoms. I just loosen and tighten the battery connections, the connections at the battery switch and the connections at the buss bars fairly often to ensure I don't end up work on strange problems related to bad connections. That's where I'd start before doing anything else.

Good luck!

I recently replaced the Yanmar i5601E display on my 4BY2-powered 2012 R27. One discovery I made is that the i5601E display is totally a NMEA 2000 device. There is no direct connection from the display to the engine. All data comes through the NMEA 2000 backbone. That other NMEA 2000 devices on your boat are encountering communication issues suggests to me that the problem may be in your NMEA 2000 backbone.

For easy access (I’m being facetious!) on my boat, the NMEA 2000 backbone is located behind the refrigerator which has to be removed for any kind of NMEA 2000 service. The backbone on my boat was a long series of single NMEA 2000 “T” connectors ganged up. I cleaned that up some with a 4-way NMEA 2000 connector. To really do the job right, I could have used another 4-way, but didn’t have it on hand. The next service I do on the NMEA 2000 backbone, I will install another 4-way.

If your NMEA 2000 backbone is the same long series of T connectors, there may be poor connectivity in one of them.

Replace the Yanmar display with Garmin GMI 20, did this about a year ago, works great, as noted above NMEA 2000 connection, way easier to read, huge improvement over old Yanmar display, but you do have to make bigger hole for GMI 20

My NMEA 2000 backbone is behind chartplotter for easier access
