Bob, The main battery power wire connected to your generator/alternator should have power on it all the time and is NOT controlled by the ignition switch. Maybe this wire was the one used for the original Ford generator and is still connected to the original voltage regulator on the firewall, is that the case? Would you be able to follow that wire along from the alternator and tell me where it connects to in the car. Possibilities are to the ammeter or under the dash somewhere. To the battery side of the starter solenoid ,a new wire not original Ford. To the voltage regulator on the firewall,original Ford wiring which terminal is it connected to on the regulator. ? Test at the alternator with your voltmeter set on DC VOLTS to see if you have power there. without ignition on or engine running. I suspect you have a wiring issue . Report back. Regards, Kevin.
