Does the constant voltage regulator need to be grounded or can it hang freely with the dash wires. Mine has come of the back of the gauge dash panel,, Thanks,,,,Dave (Catfish 50)

David, it is supposed to be grounded. Normally, it is mounted on the back side of your instrument panel. But it needs to be grounded for it to work correctly.

John is correct. Mechanical CVRs work sort of like your turn signal's flasher unit. Without a ground, constant 12-volts is output to your gauges and your sending units. Those gauges are six volt units that can tolerate 12-volts only for a short period of time before they burn out. That can be expensive.
Before 1956, Ford electrical systems were six volt, including the gauges.
In 1956, Ford switched to 12-volt, including the gauges. This turned out to be a big mistake.
For 1957, Ford went back to using 6-volt gauges WITH a CVR. This turned 12-volts on and off at 50% duty cycle, which cut the gauge current in half.Member, Sons of the American Revolution
