Boy, this is really neatr. A problem related to an honest to gosh 300 and NO arrows flying over the internet. This is exciting. Check the sense (ignition) voltage at the regulator. If it checks out at what you see across the battery, that is what your regulator is trying to maintain. Your number is about 0.6V high but that could be a measuring instrument error also. Or, very likely, your regulator, which is temperature sensitive, was not up to temp when you checked. Regulated voltage will decrease as underhood temperature, and therefore regulator temperature, increases. Check the voltage, negative battery cable terminal at the battery to the regulaor base to make sure it is near zero. Voltage check from the sense terminal at the regulator to the battery positive terminal should be zero also but won't be, but should be close. Still would suggest you drive car with eye occassionally on ammeter because if the system does have an intermittent voltage drop (unfortunately as I suspect actually) the charge rate will jump up suddenly as you are driving (not just after a stop light idle time). Good luck. Let us keep following this one.
