Sorry for the wait. I will try and help you.
It sounds like the resistor wire from the ignition switch to the + side of the coil is either not hooked up or is broken.
How this works is when the key is in the start position, the coil gets full battery voltage from the "R" terminal on the starter solenoid to help start it easier, then once the key is returned to the "run" position, the coil gets reduced voltage through a resistor wire that comes from the ign switch. The reduced voltage is to prevent the points in the distributor from burning
Are there 2 wires connected to the + side of the coil?

virtual wrench, thanks for the response. I am back to work and the earliest time I can check on this is Thursday. I waited for the so called 10 minute response but did not get it. my opportunity to check on this is over. now its Thursday. all I wanted to know when was my answer coming so that I could go to bed that night. as it turned out, I waited until 11pm even after asking for a possible time frame for the answer. again, thanks. no more dealings with just answer.
