I hope I'm in the right place to post this, but here I go...
After installing my reverse glow gauges my fuel level gauge seized working.
I'm guessing that is because I have moved it a little while the installation.
Has anyone had similar issues? Does anyone have any idea how to fix this?

 

did u check your fuses?

 

It's stuck on full. I'm not sure that a fuse would cause such a problem, but will check into it.

 

is it rubbing on the new gauge face?

 

It isn't rubbing...triple checked that. It stoped moving completely after I moved it a few degrees putting the faces on and that's where they've stopped working. All of the other gauges work allright.

 

u might have a short. check the wires.
