Guys Need some help ...Temperature Needle??

[RichiRich]

Ok....I Installed the Chrome Gauge Rings and The Silver Gauge Overlays. Here is my problem. My temperature Gauge will not rise to the normal middle mark that it always sets itself in when at normal temp. I may have knocked it when doing the install. When the car is off the needle drops all the way to the bottom. Is it supposed to do that or should it stop where the black line before the blue cold starts.. I took it for granted and never really noticed?? Second - any solutions to get this needle working correctly again. When I start the car the needle pops up but stops in the middle of the blue cold mark and does not move to middle...even after some time to get the car warm. Any suggestions or solutions would be greatly appreciated. I'm friggin spent and cant figure this one out??
