Topic: Coil adapter wiring

  I have a coil adapter that I had previously used and removed from my '37. I now want to re-install it but can't locate the wiring instructions.

Can anybody help with the instructions?

  I assume you refer to the plate that mounts where the coil used to be. If it is correct for the distributor, and the spring loaded rotor contact is OK, you should be able to just bolt it in place, and run a high tension lead from the plate to the coil.

Thanks for the response. You are correct, the plate goes on the distributor where the coil originally was mounted.

But, there should be more to the wiring. On the stock coil, there's a red wire that is attached to the top of the coil. Plus there's the condenser. I think the condenser connects to the 'connection' in the center of the plate that screws to the distributor.

I believe the red wire goes to the negative post on the new style coil. But, I don't recall where the connection from the + post on the coil goes. When I removed it 10+ years ago, I left the wire attached to the + post on the coil and the other end disconnected. Can't for the life of me recall where it was attached.

  The wire from the ignition switch goes to the input side of the coil. The other side of the coil is connected to the point terminal, as is the condenser. Of course, the high tension cable goes to the terminal that feeds the rotor. The ignition switch furnishes negative voltage,, and the other side of the coil goes to the positive ground as the points close.
