If you are using the common round coil in place of the genuine Ford coil, it is likely that coil has a builtin resistor. That requires bypassing the Ford resistor. It is important o remember that the Ford resistor also functions as a regulator. As the system voltage rises due to increased generator output, the nichrome winding of the resistor heats up, increasing resistance. As Ohm's Law says, voltage is the product of current and resistance, the points and coil are protected from damage. As for who I am, just a very old guy who loves our old Fords, and spent too many years working on them.

It makes a stronger spark during cranking only. It has nothing to do with engine cranking speed.

Is this circuit intended to enhance spark at ignition.., or increase the cranking speed of the starter?

Sounds like the OP had the circuit to the wrong side of the coil?

You are correct. this circuit won't do any good using a coil with internal resistance. But have you solved the original problem yet?

My '47 has the original coil with what looks like an external resistor as part of the unit. Will this affect how it would be wired for the "Quick Start" system?

Who or what is 'Super?"I would like to look into this fast start system.Where can I get info about it??

From the description of how this Quick Start Circuit works..., I am assuming that it only works with the OEM coil with external ballast resistor...., but will not do anything if you are using a remote 6v coil with internal resistor/resistance?

I included a test in the page to help diagnose to see if the diode was "facing" the right direction. The positive end must be facing the input of the coil. While I use the "top hat" type of diode, follow the third paragraph of the instructions to be sure. The diagram assumes that the battery is grounded at the positive pole in the original configuration, or the diode will be backward. Setting this up isn't "rocket science". That is why I put the diagram in the page.
