American Motors: 1965 Rambler Marlin will Not Shut Off, ballast resistor, soleniod

Question
Hi, I need some help. I have a 1965 Rambler Marlin with a 327 V8. My question is that even when I turn the key switch to the "off" position the car will continue to run. I have replaced the Voltage Regulator, Ballast Resistor and Key Switch and still no help. I tried to remove all the fuses and the car still runs. Please someone help me with this. I have the old Motorola Voltage Regulator Electrical System in this car "Original" and I cannot figure out why I am having this problem. Could it be a wire to the starter soleniod??? Or could it be something different? Please help me in this matter. Thanks in advance.
