i installed a water temp gauge from autometer,and when i let the car warm up it dont read right only reads 100 degrees.i got it hooked to a good ground.along with a good power source.i thought maybe the snesor that came with the gauge was bad so i went to autozone and got new sending unit and it still wont read.anyone have any ideal what is going wrong?


btw i tested the gauge by hooking it to a ground it spiked to 250 then went back down.so the gauge is working.

 

bump!
