I'm having trouble with a replacement/aftermarket temp sending unit for my '40 Tudor I purchased a few months ago from 3rd Generation Auto. When first installed, it seemed to work properly...gauge needle moved to full HOT position on the gauge when ignition is turned to OFF and worked its way to the cold side of the gauge when ignition is turned ON; then it proceeded to indicate appropriate temperature. Now, the needle moves quickly to the furthest extreme of the COLD side of the gauge and doesn't move from there when ignition is ON and returns to the HOT side when turned OFF. Is the sending unit faulty? My gauge appears to be working correctly.
