High voltage spec was set at 15.6v, anything over that was considered abnormally high, and they were also considered as industry standards. Worth noting these voltages whenever you check voltage or battery chargers.

The voltage range is set by the alternator regulator.--( around 14.4 volts. )--Much above this can be readily seen by abnormal brightness of the lights.--Also some of the older bulbs burning out.--The regulator pack is quite easy to change.--- |
