Reproduction gauge tester that works with Ford Vehicles from 1956 to 1983.
Now you can quickly determine if the gauges in your car are accurate with this gauge tester. You can verify the high medium and low reading for your gauges, and also shows that the Instrument Voltage Regulator is working.
If you own a classic Ford Lincoln or Mercury you know that the gauge readings are often not what you would expect. It's common to have the temp gauge reading hot when the car is actually not hot at all, fuel gauges that read perpetually low, or oil pressure gauges that seem to be inaccurate.
Simply unplug the sender and attach the tester with the supplied alligator clip leads, turn the ignition on, and verify the function of your gauges.
