SERVICE ENGINE ALARM/LOSS OF INSTRUMENTS

[Arctic Knight]

On my 2011 R29 with Yanmar 260 I recently developed a service engine alarm with no specific faults highlighted.
the engine appeared to continue running fine as I proceeded toward a marina. Then about an hour into the alarm and in rapid succession I lost all engine status readings (rpm/temp/oil pressure etc)and the gps service on my Garmin chart plotter. I am now in Melborne FL waiting for the local Yanmar rep to shop up and find the problem.After a night of charging on shore power all voltages are fine but upon restarting the problem has not self corrected. It has been suggested that this may all be related to low amperage and the effects thereof on solid state electronics.
any thoughts on this would be appreciated. Phone is fine as wifi here is not great.

Hello,

I have posted a few service bulletins on this engine. I would make sure that all three are corrected. Oil pressure bulletin, grounding bulletin and computer bulletin. Please look under the forum index and Ranger factory bulletins to locate.

Thank you,

The ECU is very very sensitive to bad grounding. There should be wires running from the engine battery to the ECU. Make sure that these have absolutely no corrosion and the terminals are in good shape. There are also a couple of fuses inside the unit and relays. Not sure why a fuse would blow, but make sure those connections are not corroded.
