i have the auto meter water temp i had installed and it worked fine i moved the senor and now its not working is it easy to break a water temp sensor. i was wondering if i tighten it to hard. also is the thread part aloud to move if not then it is broke cuz it does a lil bit. anybody know anything on this please hit me up.

anybody?

You mean the threaded stud where the red wire attaches to?

It's not supposed to wiggle if that's what you're asking.
If it is, it might be broken.

Not working could also be caused by a bad ground.
