Need help with car not starting!

You do need to check that the other terminal coming from the regulator the the "one" field terminal is actually controlled by the regulator as mentioned above 14.45 at idle is a little high voltage or for that matter even above idle it's high. Check the voltage @ the regulator wire going to the field. It should start decreasing in voltage as the battery reaches 13.8 to 14.2 volts, there by turning the alternator towards the no charge state. If you have a steady 12 volts or above and it's not decreasing than the regulator is not good.
