Ive installed a new water temp guage and it seems not to be working right.

 

 

 

It shows 70 degrees C no matter if the engine is stone cold, warm or if the wire isnt even connected to the sensor.

 

 

 

Any idea's?

sometimes the gauges need an addition earth off the sender try making up a wire from the sender end of the water pipe to a ground,if that fails i should imagine you have a duff gauge,there are a lot of dodgy gauges out there,best ones that always work are the plain mechanical ones or the higher spec ones like greddy defi etc

cheers greg ill have a look.

connected an earth from the sender to the car body and the guage read 150 (which is max)

Okay lets start at the begining, did the gauge read 0 before fitting ? did it come with a sensor and if so where have you fitted it ? if not what sensor are you using ? your not using any of the stock wiring are you ? and finally what make of gauge was it ?

From these answers we'll work it out ;)

Ok the guage came with a sensor, it sits at 0 when switched off, when enhine switched on it goes upto 150 the back to 70 where it stays. Its had 4 wires out of the back, Yellow (Battery) Red (Ignition) Blue (Sensor) Black (Earth). The Red, Black and Yellow wires were conncted to the ones out of the back of the stereo as they were the same colour and labeled for the same things. The blue one was to short to reach the engine bay so i connected another piece of wire to it to allow it to reach. The sensor is in a Greddy adaptor. I could not fone the screws to fit the wire to the sensor. so i wrapped the were round the thread and secured wit a nut (looks the same as is should have been). The guage is labeled Timex but i got it from the states and i think they ave now been rebadged Autometer or something.

looks like this one http://cgi.ebay.co.uk/7-Color-Glow-Phantom-52MM-Oil-Temperature-Gauge-Temp_W0QQitemZ8024689308QQcategoryZ72215QQtcZphotoQQrdZ1QQcmdZViewItem

with that gauage marcus you need to run a earth wire from the body of the sender (the outer bit with the threads that go into the adaptor) not from where the wire from the gauge mounts that should cure your prob as with the greddy adaptor the sender can't earth to give a correct reading

ohh right ill try that tommorrow, i connected it to the same bit i connected the wire to the guage to LOL. I would do it now but its snowing and im a wuss in the cold lol.

it cured the prob on mine lol

still no change :(
