strongy Posted June 21, 2006 Share Posted June 21, 2006 I have a switchable guage on my xflow and can toggle between coolant/oil temp. The oil temp no longer gives a reading, this has just happened after a recent service but that could just be coincidence. What is most likely, faulty sender on the dry sump tank Dry-sumped White Supersprint Edited by - strongy on 23 Jun 2006 11:48:16 Edited by - strongy on 23 Jun 2006 18:46:03 Link to comment Share on other sites More sharing options...
knowley Posted June 21, 2006 Share Posted June 21, 2006 Yes I'd change the sensor first! R'00 Owners Register My R300 Link to comment Share on other sites More sharing options...
I.Mupferit Posted June 21, 2006 Share Posted June 21, 2006 Don't know where your sender is sited obviously but could just be something simple like the connector becoming detached during the service and not pushed back on again. When the senders themselves fail, they normally start playing silly bu99ers and giving spurious readings rather than just failing completely. If you know where the sender is, look to see if it has a wire still attached. Brent 2.3 DURATEC SV Reassuringly Expensive R 417.39 😬 Link to comment Share on other sites More sharing options...
Jason Plato Posted June 21, 2006 Share Posted June 21, 2006 work back from the guage and check the connections any problems pop over and we can take a peek here is C7 TOP South Wales AO Link to comment Share on other sites More sharing options...
strongy Posted June 21, 2006 Author Share Posted June 21, 2006 Yes connector is attached. I'll check the wiring No warning signs of a failure - just no reading when I flip the switch Dry-sumped White Supersprint Link to comment Share on other sites More sharing options...
Chris W Posted June 21, 2006 Share Posted June 21, 2006 1. The fault can't be in the gauge or else you would have no water temp reading 2. Swap over the leads at the back of the toggle switch (ie: swap the outer 2 terminals and leave the middle one as is). If the fault now moves to the water reading and the oil now reads OK, the fault is at the toggle switch. 3. If the fault stays with the oil reading, then either the oil sender is faulty or the wiring to the oil sender is faulty. 4. Pull the wire from the top of the oil temp sender and run it (via a temporary extension wire) to the water temp sender (from which you have removed the wire at the top also). If you get a reading, then the oil temp wire is OK and the sender must be at fault. If still no reading there is a fault in the oil temp sender wire.

Mike Oxbiggar Posted June 22, 2006 Share Posted June 22, 2006 What is most likely, faulty sender on the dry sump tank?

strongy Posted June 22, 2006 Author Share Posted June 22, 2006 Update - The fault was with the coolant temp reading, not the oil - my mistake 😳 By running a wire to the oils temp sender wire to the water temp sender I get a correct reading. Fault must be the coolant temp seder wire then Job for tomorrow, off to work now ☹️ Thanks again Chris Dry-sumped White Supersprint Edited by - strongy on 22 Jun 2006 13:05:59 Link to comment Share on other sites More sharing options...

strongy Posted June 23, 2006 Author Share Posted June 23, 2006 Results so far - Old switch is working, removed it and tested as a dip/main switch - OK. When I run a wire from oil sender to water sender I can get a water temp reading, so sender ok. When I run a new wire between the switch and the water temp sender - no reading. Now I have re-connected everything - no readings at all not even oil temp now??? The only way I can now get anything at all is by running a wire from oil sender to water sender to get a water temp reading?? Very confused now??

Chris W Posted June 23, 2006 Share Posted June 23, 2006 Strongy Remove the two leads from the tops of their repective senders. Now, with the ignition ON, touch each lead in turn to ground (chassis). With the switch in one position the gauge should show full scale (ie: full over to the right) and with the switch in the other position the other lead when grounded should give a full deflection. If this doesn't happen, disconnect the switch and connect a wire from the back of the gauge (to the gauge terminal that normally goes to the centre terminal on the switch) and ground this wire with the ignition ON. If you get full deflection, your gauge is working OK and the fault is in the switch somewhere or the wiring to the switch. If the gauge does not show full deflection, either the guage is faulty or, more likely, power is not reaching the gauge for some reason. You should have 12v between the gauge's green wire (power) and the gauge's black wire (earth) with the ignition ON.

strongy Posted June 23, 2006 Author Share Posted June 23, 2006 Chris Thanks, I'm in South Wales so quite a long way away. I'll try your suggestions. I do now have oil temp after a fiddle, and like I say I can get a water temp reading via the oil temp wire, but if I run a new wire water temp sender > switch = nothing? I have also had no change fuse for heater/rev counter but I think that this is unrelated. Cheers Dry-sumped White Supersprint Link to comment Share on other sites More sharing options...

Chris W Posted June 23, 2006 Share Posted June 23, 2006 Still sounds like one bad side on the switch to me despite your having tested it. Can you swap it over temporaily with the indicator switch on the dash which is the same type? Chris 2003 1.8K SV 140hp see it here Link to comment Share on other sites More sharing options...
strongy Posted June 23, 2006 Author Share Posted June 23, 2006 I've go a spare brand new dip switch, if I can dig it out I'll give that a try Dry-sumped White Supersprint Link to comment Share on other sites More sharing options...
strongy Posted June 23, 2006 Author Share Posted June 23, 2006 Sorted now thanks. tested guage as you described all working fine. Re wired switch and tested guage now gives two readings again I reckon that I had the switch wired incorrectly i.e the power wasn't at the middle connection but at one of the ends?
