One thing I did notice was that my voltage regulator was not gounded with a wire since it mounts directly to the Rad support but when I installed a ground wire from the little blade on the back side of the regulator the GEN light got really bright. (What appears to be a normal brightness). Open for suggestions!!!!!
If your battery reads 14 volts without the engine running, then it is being heavily overcharged. A freshly charged battery, even one sitting overnight, should no more then 12.6 volts, ie, 100% charged.
The regulator chassis, frame, the gray part, should be grounded to the radiator support. The reg does bolt to the support, but, if stock, it bolts to rubber nuts for vibration purposes. The chassis should be grounded, not any terminal from the bottom of the regulator. There may have been a separate black wire from the chassis the support or ground strap about one of the mounting bolts from the old reg should have been transfered to the new reg.
With the key on, engine not running, GEN light will be bright, same illumination as the OIL light. The ignition switch supplies 12 volts to one side of the bulb. Engine starts, reg tells alt to charge, reg supplies 12 volts to other side of bulb, GEN light goes out.
