autometer water temp gauge problem

[turbie]

so i've got a little problem with my water temp gauge i put in. i wired everything up correct. it has power and a good ground. how i know it's getting power is cause when i turn the key on the gauge needle moves up just a little and in turn when i turn it off it falls down. my question is, it seems like its not getting a signal from the sensor, i have a diesel site coolant filter and i put the sensor in the top of the filter mount. should i have put it on one of the sides? or plumb it to a different place all together? i'm lost and since its been 10 degrees outside during the day, i really don't want to work on it, but its really bugging me!! thanks for any help

ive got the same problem,mine's gotta good ground and power.my gauge probe is in my dieselsite coolant filter as well.it works somtimes,most of the time it just pegs out....,i got tired of fooling with it.

maybe the probe is bad???

thanks for the quick response! well i have a oil temp gauge that shares the same power and grounding points, so i thought it could have been the water temp gauge not working, but my oil temp gauge doesn't work either. so all i can think of is either the probe is mounted in the wrong port in the filter mount. or the probe is bad. i guess i will brave the cold and switch out the probe with the oil temp probe that came with that gauge. anyone else with any ideas to help us out???

Check the resistance between the chassis, the filter housing and the probe. Could be a ground issue.

i looked at the ground, and scraped away some of the paint more so it would get a good ground. i will take it for a drive and see if it works, if not, then i guess i will check the probe.
