zulublue Posted February 16, 2009 Share Posted February 16, 2009 I am looking at fitting some LCD gauges in my D90 200TDi, I am looking at volt, water temp, oil pressure, but also oil temp now IIRC there is no gauge for this at the moment is there anywhere I can plumb one in easily?

western Posted February 16, 2009 Share Posted February 16, 2009 I fitted a LR oil temp gauge, or you can use the VDO version. have a look at here photo's of my sender units/adaptors all genuine parts. Quote Link to comment Share on other sites More sharing options...
rick Posted February 17, 2009 Share Posted February 17, 2009 Ralph, I've looked at that tee and sender in my VDO catalogue that many times now and the only thing that has stopped me doing anything is the the length of it all bouncing around out in the breeze. (to check temps I taped a thermocouple to the outside of the oil filter ) How long have you had it fitted now ? Quote Link to comment Share on other sites More sharing options...
zulublue Posted February 17, 2009 Author Share Posted February 17, 2009 Thanks Ralph, I will take a look at it, but it does look a bit long as Rick say's. Do you know the diameter of the gauges in the dashboard of a defender, I was thinking of a Mud Top console but might replace the orginals if they fit.

McS Junior Posted February 17, 2009 Share Posted February 17, 2009 Do you know the diameter of the gauges in the dashboard of a defender, I was thinking of a Mud Top console but might replace the orginals if they fit. 52mm, pretty standard gauge size.

Dave W Posted February 17, 2009 Share Posted February 17, 2009 I am looking at fitting some LCD gauges in my D90 200TDi, I am looking at volt, water temp, oil pressure, but also oil temp now IIRC there is no gauge for this at the moment is there anywhere I can plumb one in easily? A long way from being cheap but I use two of the Dual gauges from SPA http://www.spa-uk.co.uk/design/dualgauges/ As well as being extremely accurate, having dual gauges saves on space too, I've got one for water temp and oil pressure and a second for fuel level and voltage. The fuel level one can be calibrated at 6 points using the standard LR sender so is pretty accurate even if, like me, you have an odd shaped fuel tank. You can set your own warning conditions on all the gauges and, as well as the built in LED, you can operate external devices too - the water temp gauge can be used to switch your electric fans on/off, for example and you can set the temp for each.

zulublue Posted February 17, 2009 Author Share Posted February 17, 2009 ok, i've got back up now. very nice gauges there Dave but i'm looking a bit cheaper than that. I was going to fit a top mud pod and have water temp, oil pressure, oil temp and volt, but thinking about it, do I need oil temp? ok there will be a reason, I have an oil pressure light built in already, my temp gauge don't know what day it is, so swap that and I have a spare position for a volt meter. £36 for both See Here Quote Link to comment Share on other sites More sharing options...

Each to their own, the reason I want a water temp gauge is that I do not run a viscous fan, I use the X-Eng thermostat but it has never kicked in, I changed the (Block only) to a disco unit and even thought it is still the Defender temp sender it has never been the same, thus the reason for an accurate temp gauge. Oil may come at a later stage if I was comping... Quote Link to comment Share on other sites More sharing options...

western Posted February 17, 2009 Share Posted February 17, 2009 water temp will be a straight swap for the existing gauge, voltmeter [if one is already fitted] again a straight swap or just use one of the White wires from the ignition switch, then it will turn on/off with the key.

zulublue Posted February 17, 2009 Author Share Posted February 17, 2009 Ralph, should I be monitoring the return from the alternator and if so would the (white wire) do this? Quote Link to comment Share on other sites More sharing options...
western Posted February 17, 2009 Share Posted February 17, 2009 nope, you need to see what the battery state & charge state is, mine was factory fitted but I swapped to a VDO voltmeter sometime ago, with engine off it shows battery volts & engine running Alternator charge volts to battery.

zulublue Posted February 17, 2009 Author Share Posted February 17, 2009 Thanks Ralph, can you remember if it was white and some other colour as I guess there may be more than one white????? Quote Link to comment Share on other sites More sharing options...
RustyNissanPrairie Posted February 17, 2009 Share Posted February 17, 2009 I've got the standard LR Oil Temp Gauge fitted to my ex-Mil Defender 130 and I feel a lot more confident that it's letting me know what the Engine Temperature is than the inconsistent Water Temperature Guage does . I've got the additional oil temp guage fitted as standard to my ex-mil 110 2.5NA, like you say it gives a better indication of what is actually happening inside the engine. Do 70mph on a m-way and the oil temp goes upto 3/4 of the way up the guage from its usual halfway point, the water temp however never changes position once its got up to normal running temp.

So on your oil temp gauge, what is hot and what is not? Quote Link to comment Share on other sites More sharing options...
western Posted February 18, 2009 Share Posted February 18, 2009 Thanks Ralph, can you remember if it was white and some other colour as I guess there may be more than one white????? it was a plain white wire on my '89 110, it had a voltmeter from new so was connected at the factory.[some may not be connected so are spare feeds] Quote Link to comment Share on other sites More sharing options...
zulublue Posted February 18, 2009 Author Share Posted February 18, 2009 So it will be in the wiring loom even if no gauge is fitted? Cheers Ralph. Quote Link to comment Share on other sites More sharing options...
western Posted February 18, 2009 Share Posted February 18, 2009 So it will be in the wiring loom even if no gauge is fitted?Cheers Ralph. move the instrument pack & have a look from the back of the ignition switch, you should find a suitable white wire doing nothing much.

So on your oil temp gauge, what is hot and what is not? sits at half way on normal running, creeps over it slightly when doing usal 55-60 'cruising' speeds went upto 3/4 when I thrashed it in a rush the other day. The guage just has 4 lines ( i think) not numbers so I dont know what it relates to. This is on a ex-mil FFR engine with the oil cooler in the rad and the thermostatic bypass. I removed the viscous fan over a year ago and never had any water over heating problems Quote Link to comment Share on other sites More sharing options...

VDO make a tee that will allow the use of the OE sender and another for a gauge too. It looks exactly like your setup, I've just been concerned with breakage on our lovely roads out here, so I was going to braze a thermowell (a brass housing that a sender screws into) into the side of the sump.

zulublue Posted February 19, 2009 Author Share Posted February 19, 2009 Ralph, I have fitted the volt meter today to the suggested white wire, although there were a few, but I tested it first and it seemed to do the job, it was a thin gauge wire. Anyhow, I put the new gauge on the battery terminals and the battery was showing 12.4v and when the engine was running it was 14.4v. When I connected it to the white wire turned off but with ignition on it started at 12.4v but steadily dropped down to 11.8v when the engine was running it was reading up to 14.7V and dropped slightly to 14.5v with acceleration. Does this seem ok to you, what power could be lost when off connected to the white wire and gain more when running? possible drain somewhere, but nothing was on, power dropped to 14.2v with 500W of lights on. I’m not to fussed as it’s there mainly to monitor the alternator return Any ideas? Quote Link to comment Share on other sites More sharing options...
western Posted February 19, 2009 Share Posted February 19, 2009 was the 11.8v reading with ignition on but engine Off ? if yes then the drop would be caused by the glowplug system working & once they are at the right temp the timer relay shuts power off to the glowplugs, 14.4 while running is good & when items are switched on the reading will drop slightly. if there's a thicker white wire might be better to connect into that, bigger wire is able to carry more current.

zulublue Posted February 19, 2009 Author Share Posted February 19, 2009 Yes the 11.8v reading was ignition on, engine off; but it started at 12.4v and dropped to 11.8 over a few minutes I would expect the glowplugs to take their bit of required power and when at heat the relay turns off and the voltage rises, but the voltage kept on dropping to the 11.8 level. I will try it again and also put my tester on the battery to see if they match. The wire to the gauge is quite thin so I dont think attaching it to a the thicker white wire will do much. Thanks for your input Ralph. Mark. Quote Link to comment Share on other sites More sharing options...
