Run the vin through whatever decoder you fancy. If it has the regenerative braking option, it'll try to maintain battery level at around 80%, so charging will cut in and out. This is so that it can charge at full rate on overrun/braking, in order to recover maximum energy.

If you're not sure you can get a new voltage regulator for the alternator (instead of replacing the whole thing). It is often only the voltage regulator that fails.
