Can you run a 42-48 shift solenoid on 12 volt, being that it is a momentary connection.

I would run the hot wire through a resistor. G.M.

I have a new ballast resistor part # D1110-A, for a corvette, is this compatible?

I doubt that a ballest resister will carry the current.I would try the resister designed for heaters or radios. Phil

Try it and see how hot it gets. G.M.

Measure how many ohms the solenoid on the columbia control has, find a ballast resistor that has the same ohms ---use that ---the columbia solenoids are not designed to have power to them all the time --just momentary while the clutch is down,

The first generation mopar electronic ignition has a dual ballast resistor ---one or both of them can be used ---series for more ohms ---I have used these to fake out lamp modules when led lightsare retrofitted

tried a echlin ( napa) VT-6184 12-6 volt reducer, 12.2 volt in 12.2 volts out. does a volt reducer actualy drop voltage or just adjust ohm's.

Only when it is under load will you see a change in voltage, in an open circuit there will be no reduction in voltage

You have to measure voltage across the resistor. It will always show system voltage at the output end but will measure correct voltage across the resistor.
