Attached below is a schematic with instructions on the installation of a diode provided by 'supereal' a while back.

They were invented in 1906 and called crystal diodes. Selinium diodes were also available in 1939.

Probably because they didn't have solid state "diodes" back in '39.... Oops! I forgot about the selenium stacks - selenium rectifiers that were invented back in 1933....

Probably because it was not necessary.

None that I know of, unless the car is being judged, and it could be termporily removed very easily I've always wondered why Ford didn't think of this a long time before they did.

That seems very useful, hard starting or not, right? Any drawbacks?

Often someone will remove or bypass the resister to make it easier to start. if your engine is hard to start with the resister, you can run a conductor from the starter side of the solenoid, through a diode, to the hot side of the coil. This gives you full voltage to the coil while cranking, and saves wear and tear on the starter.

Yes, plan to use a 1GA-12024. I have added the under dash resistor

An internal coil resister will measure between 1 ohm and 1.2 ohms. This measurment must be taken across the primary of the coil with a high impedance Ohmmeter. 2 ballast resisters will reduce the coil efficiency. I am having a hard time understanding your problem. Are you using an original type coil with the helmet distributor or some other configuration?

Tom() I'm guessing there is no simple way to determine if a coil has an internal resistor? If an internal resistor coil is used in tandem with the under dash resistor, the result is too low of a primary circuit? Thanks for the info...
