Wiring on ignition coil - 1949 model 2365

Hello,

On the ground side of the ignition coil (positive ground), I have two wires. One that goes to the points inside of the distributor and another one that I don't know where it goes.

The wiring diagram that I have for the car does not show the extra wire. In fact, I can't find any reference to the extra wire anywhere. I was thinking that maybe it was a way to pick up engine rpm for the overdrive but I am not sure.

I changed the ignition coil and I thought I was very careful to put all wires back correctly but now I am worried that I put one of the negative 6 volt power supply wires on the positive ground side of the coil. If I did, I may be interfering with the point spark and the flyback action of the ignition coil.

The car won't start and I don't seem to have good spark. I have ordered new condensor and points even though they look good.

I think it is best to remove this wire and see if the spark is renewed in case I put it there by accident. I believe that is the safest thing to do.

If that is the case, then perhaps the wire was a 6 volt supply wire and belongs on the other side of the coil.

Obviously, I don't want to hook it up to the other side of the coil without knowing what it is.

Can anyone tell me why there would be an extra wire on the coil? And what is it supposed to supply a circuit path to?

Would there be any reason to pick up the point contact action for any other part of the circuit in the car? Like some sort of rpm counter?

If not, how can I test to see if it is supposed to be a 6 volt supply wire?

I would appreciate your comments.

Thank you,
