Model A Gauge Voltage Reducer
No need to change or modify the stock gauges or senders. Just install the electronic voltage reducer on the back of each gauge, and the gauges will continue to run on 6-volts, while the rest of the vehicle is 12-volts. Works on fuel, oil pressure, and water temperature gauges. Use all the stock 6-volt sending units. This electronic voltage reducer stabilizes the voltage output at 6-volts and eliminates fluctuations in the gauges typical with cheap resistor conversions.
