that reminds me...

my 57 Studebaker, I sold 9 yrs ago..., it ran fine, temp gauge worked as it should (at least it showed...)...showed no temp when cold , crept up to 190 as I drove it...it wasnt until a year into ownership I found out that it wasnt connected!!no wire at the connector...
the weirdest thing....who knows what temp it ran ,but the non connected gauge went to 190F....

now HOW could that be?? I never figured it out, and never connected it...
