Project Voltage Regulator
project completed can now be published.
Needing a stable source of power for 6-volt instruments after converting cars from 6 to 12 volts, I searched for a device. Numerous aftermarket sources have voltage regulators, but at $50 plus they seemed to me to be priced too high. I searched for and found a very detailed "How to do it" article on www.ford-trucks.com website and did it. Total cost was less than $10 per unit, and approximately 1 hour of my time for each unit.
now tested it in actual automotive application on a customers 53 coupe and it
works beautiful. With input voltage
varying from 11 to 14.5 volts the output was a constant 6.09 to 6.10 volts.
Perfect to power the fuel level and temperature gauges on a 53 Stude.
It will handle up to 1 amp and the gauges pulled approx. 0.7 amp. (the
amperage flow varies as the fuel level and water temperature varies).
can make this unit.
November 2012 update. I've now installed/sold 10 of these with no comebacks nor complaints.
