How do I do that ?Have you measured the resistance of the temp sensor when cold and then hot to confirm its working seem to recall low temp high reading in kilo ohm and normal run temp around 300 ohms

Thanks just popped down home for cuppa, this bloody thing is really getting to me now.
Gonna check this in morning when engine cold then check again when heated up. sender is brand new but knowing my luck probably got a knackered one.View attachment 270833if it come up out of range turn to 20k
If I wire them to where they were before the water sender just slowly goes straight up to top.you have wired them in parallel which is incorrect and does not solve your problem (do you know the temp sensor part number ) you are condemning the water pump before proving that the gauge is working correctly
remember whilst the engine is static and the wings removed the cooling effect of the fan is greatly reduced but if the coolant system is not blowing the rad cap and spewing coolant out I would sort the gauge first
don't look for problems that are not present . you can check the coolant temperature with a thermometer it should be 88 C degrees on normal operation might be slightly higher with air temperature at the moment
like I mentioned before the sender was Nightmare to find where it went on engine, once the bolt was out had to get this to fit a sender as would not fit in the threads in block.So 1162 ohms cold and 780 hot should be around 300 at normal temp ( the hotter it get the lower the resistance ) but I thought the sender was a 560794 for the Series 2
I stand to be corrected there seem to be a lot of hit and miss with the new sender hope you get to feel better what with contending with all the Chinese crap part and feeling crap with Chinese viruses
Will try the 560794 it is on here too Cylinder Head - 2.25 Litre Petrol - Find Land Rover parts at LR Workshop
Will try my local landy shop tomorrow, they might have one in stock,cannot guarantee it have ordered 560794 for mine and will try it out seem to recall some mention of the 560794 paired with the smiths temperature gauge of similar part number
here's some light reading on sensors
There is one of these on the old ambulance, 148876A - VOLTAGE STABILISER 10V NEG. EARTH JAG JENSEN LAND ROVER LOTUS MG OEM | eBay is that what you mean ? can try it if I can wire it up the right way.Have you got or can loan a voltage stabiliser you can try out looking on the smith site they list their gauges as 10 volt https://www.smiths-instruments.co.uk/landrover/series-2-and-3 so may be worth trying
No not been up yet can I just us thermometer to do that ?View attachment 271084 Try https://www.ebay.co.uk/itm/254355489190?_trkparms=amclksrc=ITM&aid=1110006&algo=HOMESPLICE.SIM&ao=1&asc=20201210111314&meid=a936c3f2bef34016989fb741b22059f1&pid=101195&rk=3&rkt% have you measured the temperature yet entering the top of the rad
Only got the one my missus took My temperature with the other day which was 39.4, she recons it was way to high, but never mind its gone back to normal now.yes if the scale is right
