Hi Paul
Higher than normal battery volts can also be caused by poor earth connection at regulator. The higher resistance earth causes a voltage drop and adds to regulator voltage. Up to 16 volts is not uncommon. Indication of problem is short lamp/bulb life and battery running dry sooner. hope this helps
