I am getting about 13.8 volts now. I am using the adjustable regulator as well. I had it on the car before I put the relay in and the voltage was around 14.6 or so. I used jumper cables to get a good ground and started the car and adjusted the regulator using my Fluke multimeter. Also I didn't mention that I ran a ground wire (just to be sure) from my alternator case to the regulator mounting screw. This mod will assure that the blue wire is at battery voltage and therefore will keep the regulator from overcharging your battery. I believe that the real problem here is dirty/ worn out ignition switch contacts, but this will keep you from having to replace the switch. Let me know if you need help
