Temp Gauge

I cant figure out my temp gauge. It worked great last summer now it goes from cold to pegged hot after about a minute of idling. Changed the sender and still the same thing. The cooling system seems to be working fine. Any ideas? Thanks for your help

I suppose it could be a bad gauge but I would suspect a bad ground, either from the gauge cluster to the dash, or from the frame to the cab, or from the motor to the cab, or from the motor to the frame. There should be ground straps on all of those.
