Convert from Idiot warning lights to analog gauges or NMEA2000 compatible data

Hello,

I have a 23 year old Yanmar 3gm30f engine. Temperature and oil pressure warnings are just idiot lights on my ignition panel. I am looking to upgrade that to actual analog gauges or into my NMEA 2000 compatible MFD (Zeus 3). I am not sure which is the easier route. I also have completely no idea how to do this.

Has anybody done this? Could you point me in the right direction on where to get information and what products are used?


Thanks.

Re: Convert from Idiot warning lights to analog gauges or NMEA2000 compatible data

I can't comment on your specific engine, but on the similar aged Volvo's we've owned, all wires for all versions of instrument panels were in the wire harness. When I converted ours from idiot lights to actual gauges, all I had to do was buy the sensors and gauges, and connect up the corresponding wires that already existed in the Volvo wire harness. Teleflex and VDO are two manufacturers of sensors and gauges.

If yours is similar, then this is a pretty easy thing to do.

For NMEA2000, you will need the sensors anyway, then you will need an analog-N2K device like those from Actisense or AlbaCombi (there are probably others), as well as a device to read/display the data, like a chartplotter or small MFD, or dedicated display - I see you intend to use your Zeus. This is really only slightly more complicated, but it is more expensive.

Another analog->NMEA 2000 adaptor is a Noland RS11, which is slightly less expensive than the options listed above.

Yanmar makes both a temperature gauge and oil pressure gauge kit. They are not all that expensive. I would check with your local Yanmar shop.

Here's an article on the oil pressure gauge using non-OEM parts

And here are all of the gauges....(you will need to check if the sensors/sending units are included)
