Adding Indicators

[LADY JANE]

2014 / R-21EC / D1-30 needs the addition of two basic Indicators onto it's Garman screen: Temp Gauge and Voltmeter. Does anyone have the parts manual and/or maintenance manual for this model? P/N's and installation procedures for these indicators would be very helpful. -Bill

2014 Manuals are hard to find, new or used.

Hello Bill,

I can set one of the 'data' blocks to read "volts" on my Garmin. Which GArmin to you have?

Having Oil Pressure gauge would be nice. I've seen others add them by installing a 'T' where the current oil pressure sender is located, then relocating the original to one limb of the T and installing another for their new gauge on the other limb of the T.

The D1-30 engine has been in production since 2010 so shop manuals should be available. Check with your parts dealer as they should be able to order one.

Lady Jane:

I just recently added as many manuals as I could to my computer and found the job, although time consuming, of finding them easy in most cases. I did a search for "Volvo D1-30 and came up with the link below, I hope this helps.

Thanks Jim & Dave. I have the Garman 7. Will put "T" fittings in for the pressure gauge and the oil temp that should percolate good readings. BB+

Thanks Dave, I have the Garman 7... Will put a "T" fitting in and the temp gauge should percolate on the next trip.

Hello Bill,

Let us know how the "T" setup works...please include the parts you use and source. Someone might want to duplicate your system.

Does adding a T and than temp work well? My brain tells me that oil doesnt flow through that so oil temp would slow to respond and not accurate since it can only read the temp of the oil in the line after the T and not whats actually flowing im the engine. For pressure of course it doesnt matter.

I'm not too sure about all that with a mechanical gauge. I'll just go with an electric oil temp gauge with an electric "Y" sensor. It'll have accurate readings and will avoid any possibility of oil leaking at the dashboard. BB+

Wasnt talking about mechanical gauges. What the heck is an electric "Y" sensor? Oil still needs to touch a sensor to sense temp, unless these are magical gauges of some kind.

I'm not too sure about "magical gauges" but am just adding an electrical oil temp gauge that is kind of "magical" in a way. It will have a common electrical oil temp sensor with 2 electrical connectors (on it) for 2 separate temp indicators, like an idiot light, a separate gauge, or a Garman, etc.to that one sensor.

I'm not too sure about "magical gauges" but am adding an electrical oil temp gauge that is kind of "magical" in a way. It will have a common electrical oil temp sensor with a ("Y" split) connector. That way 2 different indicators can be added, like an idiot light, a separate gauge, or a Garman, etc.

I think maybe you dont understand how it works. The original pressure sensor is screwed into a threaded hole, in contact with oil. If you replace that sensor with a T fitting and than reinstall the pressure sensor, it will work as normal since its only reading pressure. Adding a temp sensor on the other end of the T is what im questioning... It will not be in contact with flowing oil, it will only be in contact with whatever oil manages to fill the T, it will not be flowing since there is no in/out for the oil to travel. It may be better to install a bung on an external oil line if one exists so you can place the temp sensor inline with the actual flow of oil.

If we talking about mechanical gauges you would 100% need a supply and return oil line to the gauge, not just a single line like a pressure gauge would require.

If you use a T fitting and than place the oil temp, you could just be reading ambiant air temperature around the engine if the oil in the T fitting manages to cool enough, remember... Its not flowing through that fitting, its got nowhere to go.

 

[LADY JANE]

I hope there won't have to be any other extra fittings or anything else added to the oil temp installation but a separately wired gauge, a new sensor with (hopefully) 2 contacts/connectors, and fused power. It should work OK...unless I'm forgetting something??? BB+

Thanks Jim F./Kismet, for providing the valuable link to this electrical subject! And thanks to all you Tugnuts who keep us thinking in the right direction.

The next most important indicator additions to the R-21EC helm will be for monitoring our batteries' voltage BEFORE engine start-up. A small Voltmeter needs to be wired to each of our main battery switches. It was also suggested to wire up a low voltage warning light to each battery, to warn us of voltage below the 12 Volt mark.
A momentary toggle (horizontally) selector switch will alternate the voltmeter between #1 & #2 batteries for separate voltage readings. The Low Voltage Warning Lights are wired separately with toggle switches directly to each 12 volt battery. Have any Tuguts added these indicators to their R21-- helm? If so, or if not, any electrical Tips/Suggestions/Ideas/etc. are WELCOME!
Thanks,
-Bill- & the Lady Jane

One word of caution:
In my recent Tugnuts posting "Yanmar 4BY2 Oil Pressure" there was discussion regarding tees additional sensors. One person who had done this recounted a problem he had. The extra mass and extended piping for the other sensors were subject to vibrations that fatigued the pipe fitting. The fitting broke and the engine dumped all it's oil into the bilge. Not a good thing.
