What do you get on the gauge with the sender wire disconnected. It should read empty?
In order to read full hot the terminal that the sender unit wire connects to has to be grounded. It sounds like the gauge terminal is grounded , or the circuit board strip that feeds it is . You know that the terminal posts are insulated from the dash with little insulators. Below is the readings you should get at the gauge.
