I finally tried to start my engine yesterday. Engine last ran in 1978 and I rebuilt it last summer. I have installed the painless wiring system. It would not fire and I found that there was no juice going to the coil as I cranked the engine. There is juice with the key on, but not while cranking. I jumpered a lead from battery positive to coil positive and was able to fire her up (only for a second, I am not ready to run her yet, but couldn't wait to see if she would light up). It's a 69 and there are only two wires to the starter, the battery positive and the connection from the ignition to the S terminal. I have gone with a one wire alternator. There is no ballast resistor in this circuit. Should I run a lead from the S terminal to the coil to get juice while cranking or is there a connection I missed somewhere? I am planning on removing the points and putting in the Pertonix Ignitor after I have her fired and the cam broken in.

I use the juice coming from ignition switch right after the switch. You can splice right into the pink wire for the ignition. You can also use the IGN prong in the center of your fuse box. These are the only two that stay hot while cranking.

The original wiring harness and switch have (at the ignition switch) one terminal that will send power to the coil when cranking only (thru normal wire) to the bulkhead connector, and a second terminal that will power the coil during "run" feeding the resistor wire. Both wires meet at the same terminal on the bulkhead connector and pass thru to the (black pink if I remember right) wire that goes to the coil on the engine side.
Hope this helps.

Thanks guys, that helps a lot. I'll have this beast running by the end of the summer, finally.

is it apple juice or orange juice your missing?
