Do you have an ohm meter? If so, disconect the wire from the sender and check
for
resistance between the screw terminal on the sender and the hex case of the
sender.
If there is some reading (not over something in the K Ohm range) the sender is
probably OK.
The sender is about the only thing youcan't check with a test light and a
little thought,
without starting the engine and warming it up.
If you ground the test light to the engine block and touch the screw on the
sender (with
the wire connected, you should get a gauge indication. Move the test light to
the case of
the sender and, if the ground is OK, get no change. If the gauge indicates
something then
the sender is not grounded well enough. Next touch the test light to the
elbow. If the
gauge reads something then the elbow is not brounding to the engine. If not,
then you have
something really wierd wrong and need to get a second opinion.
If you didn't get an indication when you had the test light connected to the
wire to the
gauge, you either have a bad connection in the wireing between the sender,
gauge, dash
regulator and power, a defective gauge, or dash regulator.
Good hunting.
