What is this?
Hi All,
The car is 1947 ford sedan mostly original. This part is under the dash on the upper left corner of the firewall. It has no visible wires attached. I would like to know what it is before I take it out. Thanks for your help. Brian |

Re: What is this?
It's the circuit breaker/resistor board. The resistor steps down the voltage to the coil and the circuit breaker takes the place of a fuse for your lights etc.....

Re: What is this?
Yes, ballast resistor and circuit breakers. On a 47 there should be two circuit breakers inside the enclosure, both for the lighting circuits. If it is not connected there must be some major wiring changes. I would guess an added fuse panel and a "can" style coil in place of the original coil. Is it 6v or 12v? Positive ground or negative ground?

Be very careful not to damage it when you remove it.

Re: What is this?
Thanks for your replies. I took it out and there was in fact no wires attached to it.
I took a picture of where those heavy gauge yellow wires go to. They are attached to a brown rectangular terminal block which is screwed onto the backside of the gauge cluster panel. Is this an after market solid state circuit breaker? |

Re: What is this?
Does the car with this wiring run?

Re: What is this?
Yes, it runs just fine with all electrical components okay. It’s original 6 volt positive ground. Just want to know what I’ve got.

I hope there is a fuse in there somewhere.

Re: What is this?
Why remove it ? How many miles on the car ? How many volts at the coil ?

Re: What is this?
I've seen that setup before, it is similar to the 48-49 truck wiring. The first photo is labled as a 47. The device shown is the circuit breakers (2) and a resistor is not needed with the can coil.

Re: What is this?
I have the same set up as Rockbass with the resistor attached to the original coil under the hood. The dash set up consists of a junction block with circuit breaker. This is a 6v + ground system, late '47 (Nov) super deluxe 4 door sedan.
Could this be one of Ford's "running changes"!!??

Re: What is this?
JSeery, I think you nailed it, thanks for sharing your knowledge. Wow, what a great resource this Fordbarn forum is. Oh, one more quick question, what is a “can” style coil?

Re: What is this?
The can style coil is the round coil used on the later cars.
