RE: really puzzled
It could possibly be some resistance in the wires between the sender
unit and the computer. I believe you can remove the connector from the
computer and check the resistance between the pins that go to the temp.
sender (I don't have the Bently for the 4k anymore but if you don't have
it I'm sure someone on the list can give you the pin #'s)
It is possible that with the wires shorted that the resistance was close
to what is supposed to be coming from the sender this making it run
"normally". I believe the Bently procedure is with the temp. sender
installed but you could easily short the wires at the sender end and
measure the true resistance of the wire - should be essentially 0 ohms.
Also, wiggle the connector back and forth while watching the readings to
check for shorts/opens.
