RB25DET: hooking up water temp?????

[whoareu]

ok so ive hooked up my temp guage and im wondering if it is operateing corectly. with the ground hooked up it registers 100, and when the ground isnt hooked up it reads like 150. however the stack gauge reads it is overheating. i definatly dont think its overheating, but at the same time its scary. does the temp sender need to be grounded. its an autometer guage if that helps.

wow, really, so no one has hooked up an autometer temp guage.

150ºf or 150º celsius?
I think it may be celsius and that is quite hot. 150º celsius equals about 302º fahrenheit, I think.

Have some patience.
Does it have its own sensor?

ok so it doesnt say this in the intructions, but if you are using an adapter like i am (greddy water temp adapter in the upper rad hose) then the adapter must see a ground. and you can not just simply ground the sender. just a little fyi, as i know quite a few people with this problem. Apperantly the sender see's ground through the threads on the sender itself.

i installed a mechanical auto meter water temp gauge with their hose adapter kit. it had a screw and lead for a ground if it was a electronic guage.

Really? Never heard of the adapter needing a ground. Since temperature sensors arent powered...

[whoareu]

me neither, but aparently they do.

[Joel 180]

says who? Mine worked just fine ungrounded

[whoareu]

ummm auto meter. where is your sender placed?

[Joel 180]

In a custom adapter in the top radiator hose.

Do you have this one? http://www.autometer.com/download_instruction/771d.pdf
It says to ground the temperature sensor module but says nothing about grounding the adapter or sensor itself.
