Short answer is NO.

That was a Ballast Resistor on the old engines to drop the voltage after start to help not burn points. I believe it dropped the voltage to about 9V but could be wrong. Voltage to the coil came from the starter solenoid during crank, then through the Ballast Resistor with the key in "Run".

Check your alternator and your wiring like 34_40 suggests.
