[QUOTE="jarance, post: 353975, member: 21"] Additional Information about the alternator. How does your alternator work. basically, it convert an Alternating Current (AC) to Direct Current (DC) via a rectifier bridge. The output voltage voltage will depends on the speed of the engine. Hence the faster the speed the higher the voltage. The voltage regulator will regulate the voltage to within a limited for the proper charging of the battery. if this voltage is not regulated, the battery would be damaged due to overvoltage. See pic below. [IMG]http://i122.photobucket.com/albums/o271/pbjy/alternator/principleofalternator.jpg[/IMG] [/QUOTE]
