Joe, Glad you are on a role.
I have a stock alternator and not a one wire connection, with the car in idle I am getting 12.4 volts, my alternator relay is working just fine, I have a new regulator and that is also working fine, the ignition light comes on when the car is switched on, and every thing is connected appropriately to the speedometer. All checks out and works well except the ignition light comes on from time to time when I am driving.
