The
primary electrical
power source is a 12-volt. 60-amp alternator. which is protected by
a voltage regulator and an overvoltage relay. The alternator provides full electrical power output
even at low engine RPM. This provides improved radio and electrical equipment operation and
increases battery life oy reducing battery load.
