I check them with a 12v DC power supply on the work bench.
12v + to the "B" terminal of the gauge, 12v- to the body of the gauge
(ground)
Also 12v- to the body of the sender and a wire from the terminal of the
sender to the "T" post on the gauge.
Now slowly move the float up and down and watch the gauge.
99 out of 100 times, it's a bad sender.
The 73 does have a voltage stabilizer in line from the battery to the
gauge, you do not need this to bench test the set up but the readings
will be off a little without it.
If you get an empty reading on the bench with the float down, and a full
reading with it up, it's good.
