Constant Voltage Regulator for 1969-1973 Mustangs.
This new constant voltage regulator features solid state technology for smooth gauge performance with no adjustment needed. Original units use mechanical contacts that open and close causing gauges to fluctuate needing to be adjusted manually with a screw driver.

I have a 70 mustang mach 1 and I believe it has a replacement constant regulator. Problem is gauges work when you start the car, then shut off in a short time. I don't know if it is the regulator or circuit board. How can I test to find out the problem.
in my 69 mach1, I have no left turn signal in the temperature gauge and no lights in the temp gauge or speedometer. I have power to the plug in both blue/red wire and blue wire. is this a voltage regulator issue or circuit board?
It used to say"open and turn 180 degree". Has that changed and how do I know mine is the "new" or the old "one". All I can say is it perfectly fits on the circuit board, the 2 contacts are at the same position like at the original one? Thanks
