I believe 30 ohms when full, zero ohms when empty is correct for the '62. Jump the wire at the sending unit to ground and turn on the key. If the gauge still reads full the wire that runs from the gauge to the sending unit is bad. If the gauge reads empty either the sending unit is bad or it is not properly grounded.
