Resistor Coil

[tubman]

Now that we have all the information, we can consider the original question.

I am rewiring my 40 Ford and I see there is an ignition resistor on the board with circuit breaker and my question is do I now buy a non resistor coil?"

My advice, since you are essentially using an 8BA engine, is to bypass the '40 ignition circuitry completely and just run the ignition lead to the 8BA (or compatible) coil. 8BA's did not use a resistor coil. I believe a Bosch "Blue" coil from a Volkswagen is an acceptable substitute.

A Bosch blue coil is a 12 volt coil with an internal resistor.

It has been a while; but if I remember right the post '49 cars used a 6 volt coil an internal resistor.

Guess you have a choice of a non-resistor 6 volt coil retaining the firewall mounted resistor or a internally resisted 6 volt coil and jump the firewall resistor.

Might come down to a choice of which coil is available.

If the one you chose comes from Mexico or China; maybe get two and carry the extra in your trunk.

Quality of this stuff has really gone downhill; just saying.
